MFC r251634: illumos #3745 zpool create should treat -O mountpoint and -m the same
cddl/contrib/opensolaris/cmd/zpool/zpool_main.c: (change 644608) This allows specifying a mountpoint using the latter form and having its value checked and used as it would be using the former form.
As a consequence of this change:
1. The mountpoint property is set in the fsprops nvlist prior to creating the pool, rather than being set after creating the pool. To me, this is the proper approach, since it avoids creating the pool if the mountpoint setting would cause the command to fail. 2. The mountpoint property, unlike all others, can be specified more than once. Only the last setting takes effect. This is to avoid breaking potential existing users that specify -m more than once.
Submitted by: will
cddl/contrib/opensolaris/lib/libzfs/common/libzfs_pool.c Fix "zpool create -R <whatever> -m <whatever>". Ever since change 644608, this has been broken. The problem is that some old code in libzfs_pool.c would force a pool's mountpoint to "/" when creating a pool with an altroot. That probably implemented some old policy decision regarding altroots, but it conflicts with the current manpage. It also had no effect until 644608, because the zpool command would _always_ change the pool's mountpoint after creating it. The solution is to delete the old code from libzfs_pool.c.

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 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.

MFC r240870 (pjd): It is possible to recursively destroy snapshots even if the snapshot doesn't exist on a dataset we are starting from. For example if we have the following configuration:
tank tank/foo tank/foo@snap tank/bar tank/bar@snap
We can execute:
# zfs destroy -t tank@snap
eventhough tank@snap doesn't exit.
Unfortunately it is not possible to do the same with recursive rename:
# zfs rename -r tank@snap tank@pans cannot open 'tank@snap': dataset does not exist
...until now. This change allows to recursively rename snapshots even if snapshot doesn't exist on the starting dataset.

MFC r245264:
The current ZFS code expects ddt_zap_count to always succeed by asserting the underlying zap_count() to return no errors. However, it is possible that the pool reaches to such a state where zap_count would return error, leading to panics when a pool is imported.
This commit changes the ddt_zap_count to return error returned from zap_count and handle the error appropriately. With this change, it's now possible to let zpool rollback damaged transaction groups and import the pool.

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.

ZFS tries to allocate blocks evenly across all devices. This means when devices are imbalanced zfs will lots of CPU searching for space on devices which tend to be pretty full. It should instead fail quickly on the full devices and move onto devices which have more availability.
New loader tunable: vfs.zfs.mg_alloc_failures (min = 8)

Correct reporting of missing leaf vdevs so that the GUID required to perform pool actions is always displayed.
cddl/contrib/opensolaris/cmd/zpool/zpool_main.c: The "zpool status" command reports the "last seen at" device node path when the vdev name is being reported by GUID. Augment this code to assume a GUID is reported when a device goes missing after initial boot in addition to the previous behavior of doing this for devices that aren't seen at boot.
cddl/contrib/opensolaris/lib/libzfs/common/libzfs_pool.c: In zpool_vdev_name(), report recently missing devices by GUID. There is no guarantee they will return at their previous location.

Add a new "REFCOMPRESSRATIO" property.
For snapshots, this is the same as COMPRESSRATIO, but for filesystems/volumes, the COMPRESSRATIO is based on the data "USED" (ie, includes blocks in children, but not blocks shared with the origin).
This is needed to figure out how much space a filesystem would use if it were not compressed (ignoring snapshots).

Add libdtrace support for tracing userland programs.
Summary of changes: * Implement a compatibility shim between Solaris libproc and our libproc and remove several ifdefs because of this. * Port the drti to FreeBSD. * Implement the missing DOODAD sections * Link with libproc and librtld_db * Support for ustack, jstack and uregs (by sson@) * Misc bugfixing
When writing the SUWN_dof section, we had to resort to building the ELF file layout by "hand". This is the job of libelf, but our libelf doesn't support this yet. When libelf is fixed, we can remove the code under #ifdef BROKEN_LIBELF.

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.
Submitted by: dfr
- 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.
Submitted by: trasz
- Creation-time properties
- Regression tests for zpool(8) command.

Use provider's ident to handle situations when disks are moved around and show up with different names: first try to open provider using remembered name and compare its ident, if equal, this is our provider, if not equal or there is no provider with such name, find provider with remembered ident and don't care about the name.

MFp4:
@118370 Correct typo.
@118371 Integrate changes from vendor.
@118491 Show backtrace on unexpected code paths.
@118494 Integrate changes from vendor.
@118504 Fix sendfile(2). I had two ways of fixing it: 1. Fixing sendfile(2) itself to use VOP_GETPAGES() instead of hacking around with vn_rdwr(UIO_NOCOPY), which was suggested by ups. 2. Modify ZFS behaviour to handle this special case.
Although 1 is more correct, I've choosen 2, because hack from 1 have a side-effect of beeing faster - it reads ahead MAXBSIZE bytes instead of reading page by page. This is not easy to implement with VOP_GETPAGES(), at least not for me in this very moment.
Reported by: Andrey V. Elsukov <bu7cher@yandex.ru>
@118525 Reorganize the code to reduce diff.
@118526 This code path is expected. It is simply when file is opened with O_FSYNC flag.
