MFC r251631: illumos #3742 zfs comments need cleaner, more consistent style
- Make more of ZFS's comments use a natural English writing flow. - Break up long paragraphs, fix various typos and spelling errors. - Don't prefix a function description with its name when the function definition immediately follows. - Remove useless comments. - Add extra whitespace where it makes the comments more readable.
New comments were separated from this change and added in r251629.

MFC r251629: 3741 zfs needs better comments
Embellish the comments in various components of ZFS. Move some comments around closer to what they describe. Specifically, answer the questions:
- What are some of the edge cases of the dbuf state machine? - What does a txg quiesce do? - When does the DMU notify threads waiting on txg's that they may proceed? - How do the calculations for RAIDZ map allocations work? - What process do the RAIDZ I/O start and done callbacks follow?
While here, adjust the function prototype of dmu_zfetch.c:dmu_zfetch_colinear() to match its comment which describes its return as a boolean.

Merge libzfs_core and other ZFS bugfixes and improvements.
MFC r248571: MFV 238590, 238592: In the first zfs ioctl restructuring phase, the libzfs_core library was introduced. It is a new thin library that wraps around kernel ioctl's. The idea is to provide a forward-compatible way of dealing with new features. Arguments are passed in nvlists and not random zfs_cmd fields, new-style ioctls are logged to pool history using a new method of history logging.
http://blog.delphix.com/matt/2012/01/17/the-future-of-libzfs/
MFV 247580 [1]: To address issues of several deadlocks and race conditions the locking code around dsl_dataset was rewritten and the interface to synctasks was changed.
User-Visible Changes: "zfs snapshot" can create more arbitrary snapshots at once (atomically) "zfs destroy" destroys multiple snapshots at once "zfs recv" has improved performance
Backward Compatibility: I have extended the compatibility layer to support full backward compatibility by remapping or rewriting the responsible ioctl arguments. Old utilities are fully supported by the new kernel module.
Forward Compatibility: New utilities work with old kernels with the following restrictions: - creating, destroying, holding and releasing of multiple snapshots at once is not supported, this includes recursive (-r) commands
Illumos ZFS issues: 2882 implement libzfs_core 2900 "zfs snapshot" should be able to create multiple, arbitrary snapshots at once 3464 zfs synctask code needs restructuring
MFC r248976: Call dmu_snapshot_list_next() in zvol.c with dsl_pool_config lock held

MFC r249195: Merge change from vendor to reduce diff only. ZFS dtrace probes are not supported on FreeBSD yet.
Illumos ZFS issues: 3598 want to dtrace when errors are generated in zfs
MFC r249196: Provide a fix for kernel panic if receiving recursive deduplicated streams. Problem reported to vendor.
Illumos ZFS issues: 3692 Panic on zfs receive of a recursive deduplicated stream
MFC r249206: Merge vendor change - modify time processing in deadman thread.
Illumos ZFS issues: 3618 ::zio dcmd does not show timestamp data
MFC r249207: Allow zdb to output a histogram of compressed block sizes.
Illumos ZFS issues: 3641 want a histogram of compressed block sizes
MFC r249319: ZFS expects a copyout of zfs_cmd_t on an ioctl error. Our sys_ioctl() doesn't copyout in this case.
To solve this a new struct zfs_iocparm_t is introduced consisting of: - zfs_ioctl_version (future backwards compatibility purposes) - user space pointer to zfs_cmd_t (copyin and copyout) - size of zfs_cmd_t (verification purposes)
The copyin and copyout of zfs_cmd_t is now done the illumos (vendor) way what makes porting of new changes easier and ensures correct behavior if returning an error.
MFC r249326: Cast (void *)(uintptr_t) on copyout and copyin of zfs_iocparm_t.zfs_cmd
MFC r249356: Merge bugfixes accepted and integrated by vendor. Underlying problems have been reported by us and fixed in r240942 and r249196.
Illumos ZFS issues: 3645 dmu_send_impl: possibilty of pool hold leak 3692 Panic on zfs receive of a recursive deduplicated stream
MFC r249357: Fix libzfs to report error instead of returning zero if trying to hold or release a non-existing snapshot of a existing dataset. In recursive case error is reported if no snapshots with the requested name have been found.
Illumos ZFS issues: 3699 zfs hold or release of a non-existent snapshot does not output error

MFC r226676, r226678, r226700, r226705, r226706, r226707:
MFC r226676 (pjd): Allow to rename file systems without remounting if it is possible. It is possible for file systems with 'mountpoint' preperty set to 'legacy' or 'none' - we don't have to change mount directory for them. Currently such file systems are unmounted on rename and not even mounted back.
This introduces layering violation, as we need to update 'f_mntfromname' field in statfs structure related to mountpoint (for the dataset we are renaming and all its children).
In my opinion it is worth it, as it allow to update FreeBSD in even cleaner way - in ZFS-only configuration root file system is ZFS file system with 'mountpoint' property set to 'legacy'. If root dataset is named system/rootfs, we can snapshot it (system/rootfs@upgrade), clone it (system/oldrootfs), update FreeBSD and if it doesn't boot we can boot back from system/oldrootfs and rename it back to system/rootfs while it is mounted as /. Before it was not possible, because unmounting / was not possible.
MFC r227768 (pjd): Include <sys/zfs_vfsops.h> only when compiling kernel module.
MFC r226700 (pjd): Don't forget to rename mounted snapshots of the file system being renamed.
MFC r226705 (pjd): Extend r226676 to allow rename without unmount even for file systems with non-legacy mountpoints. It is better to be able to rename such file systems and let them be mounted in old places until next reboot than using live CD, etc. to rename with remount.
This is implemented by adding -u option to 'zfs rename'. If file system's mountpoint property is set to 'legacy' or 'none', there is no need to specify -u.
Update zfs(8) manual page to reflect this addition.
MFC r226706 (pjd): Update copyright to include myself.
MFC r226707 (pjd): - Use better naming now that we allow to rename any mounted file system (not only legacy). - Update copyright to include myself.

Handle cases where virtual (GFS) vnodes are referenced when doing forced unmount. In that case we cannot depend on the proper order of invalidating vnodes, so we have to free resources when we have a chance.

- Mount ZFS snapshots with MNT_IGNORE flag, so they are not visible in regular df(1) and mount(8) output. This is a bit smilar to OpenSolaris and follows ZFS route of not listing snapshots by default with 'zfs list' command. - Add UPDATING entry to note that ZFS snapshots are no longer visible in mount(8) and df(1) output by default.

If we have to use avl_find(), optimize a bit and use avl_insert() instead of avl_add() (the latter is actually a wrapper around avl_find() + avl_insert()).
Fix similar case in the code that is currently commented out.

When snapshot mount point is busy (for example we are still in it) we will fail to unmount it, but it won't be removed from the tree, so in that case there is no need to reinsert it.
This fixes a panic reproducable in the following steps:
# zfs create tank/foo # zfs snapshot tank/foo@snap # cd /tank/foo/.zfs/snapshot/snap # umount /tank/foo panic: avl_find() succeeded inside avl_add()

getcwd() (when __getcwd() fails) works by stating current directory, going up (..), calling readdir and looking for previous directory inode. In case of .zfs/ directory this doesn't work, because .zfs/ is hidden by default, so it won't be visible in readdir output.
Fix this by implementing VPTOCNP for snapshot directories, so __getcwd() doesn't fail and getcwd() doesn't have to use readdir method.
This fixes /bin/pwd from within .zfs/snapshot/<name>/.

Remove the thread argument from the FSD (File-System Dependent) parts of the VFS. Now all the VFS_* functions and relating parts don't want the context as long as it always refers to curthread.
In some points, in particular when dealing with VOPs and functions living in the same namespace (eg. vflush) which still need to be converted, pass curthread explicitly in order to retain the old behaviour. Such loose ends will be fixed ASAP.
While here fix a bug: now, UFS_EXTATTR can be compiled alone without the UFS_EXTATTR_AUTOSTART option.
VFS KPI is heavilly changed by this commit so thirdy parts modules needs to be recompiled. Bump __FreeBSD_version in order to signal such situation.

Update ZFS from version 6 to 13 and bring some FreeBSD-specific changes.
This bring huge amount of changes, I'll enumerate only user-visible changes:
- Delegated Administration
Allows regular users to perform ZFS operations, like file system creation, snapshot creation, etc.
- L2ARC
Level 2 cache for ZFS - allows to use additional disks for cache. Huge performance improvements mostly for random read of mostly static content.
- slog
Allow to use additional disks for ZFS Intent Log to speed up operations like fsync(2).
- vfs.zfs.super_owner
Allows regular users to perform privileged operations on files stored on ZFS file systems owned by him. Very careful with this one.
- chflags(2)
Not all the flags are supported. This still needs work.
- ZFSBoot
Support to boot off of ZFS pool. Not finished, AFAIK.

- Snapshot properties
- New failure modes
Before if write requested failed, system paniced. Now one can select from one of three failure modes: - panic - panic on write error - wait - wait for disk to reappear - continue - serve read requests if possible, block write requests
- Refquota, refreservation properties
Just quota and reservation properties, but don't count space consumed by children file systems, clones and snapshots.
- Sparse volumes
ZVOLs that don't reserve space in the pool.
- External attributes
Compatible with extattr(2).
- NFSv4-ACLs
Not sure about the status, might not be complete yet.

- Creation-time properties
- Regression tests for zpool(8) command.

Introduce accmode_t. This is required for NFSv4 ACLs - it will be neccessary to add more V* constants, and the variables changed by this patch were often being assigned to mode_t variables, which is 16 bit.

VOP_LOCK1() (and so VOP_LOCK()) and VOP_UNLOCK() are only used in conjuction with 'thread' argument passing which is always curthread. Remove the unuseful extra-argument and pass explicitly curthread to lower layer functions, when necessary.
KPI results broken by this change, which should affect several ports, so version bumping and manpage update will be further committed.

vn_lock() is currently only used with the 'curthread' passed as argument. Remove this argument and pass curthread directly to underlying VOP_LOCK1() VFS method. This modify makes the code cleaner and in particular remove an annoying dependence helping next lockmgr() cleanup. KPI results, obviously, changed.
Manpage and FreeBSD_version will be updated through further commits.
As a side note, would be valuable to say that next commits will address a similar cleanup about VFS methods, in particular vop_lock1 and vop_unlock.

Reimplement traverse() helper function: 1. Pass locking flags to VFS_ROOT(). 2. Check v_mountedhere while the vnode is locked. 3. Always return locked vnode on success.
Change 1 fixes problem reported by Stephen M. Rumble - after zfs_vfsops.c,1.9 change, zfs_root() no longer locks the vnode unconditionally and traverse() didn't pass right lock type to VFS_ROOT(). The result was that kernel paniced when .zfs/ directory was accessed via NFS.
