changed ioctl hook return code when the opcode isn't supported.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40784 a95241bf-73f2-0310-859d-f6bbb57e9c96

added a file system call preallocate() as described in #6285, currently unused


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39006 a95241bf-73f2-0310-859d-f6bbb57e9c96

Changed the type of the "op" parameter of the fs_vnode_ops::ioctl() hook and
the _kern_ioctl() syscall from ulong to uint32.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36927 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The volume init wasn't checked, so a failed init would crash.
* Unlocking a removable drive was done in the wrong error label which would've
resulted in accessing deadbeef due to the volume being freed just before its
use or using the not initialized volume variable.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36103 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Applied slightly cleaned up patch by romain that sanitizes the volume names.
* This closes bug #4602.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35523 a95241bf-73f2-0310-859d-f6bbb57e9c96

Applied patch by romain. Through refactoring, the volume name is already
retrieved before a volume is actually mounted and this fixes #4602. I have
applied the patch as is, although it contains some minor coding style violations,
since these have been there before.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35262 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Removed the superfluous "magic" stuff - if structures are broken, then please
let it crash!
* Made some headers self-contained.
* Always lock, regardless of "reenter" (we're using a recursive lock, so this
doesn't matter at all).
* Some cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31913 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced diri_mark_dirty() with a diri_make_writable(), and fixed its usage
throughout the code.
* Got rid of the transactions - they weren't really used, and thus only created
unnecessary overhead.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31836 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Cleanup.
* The active fat field is valid if fats aren't mirrored, not the other way
around.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31257 a95241bf-73f2-0310-859d-f6bbb57e9c96

- Remove left-over debug output.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30838 a95241bf-73f2-0310-859d-f6bbb57e9c96

- Fix renaming a FAT volume.

Note that this does not fix the fact that the volume name can be in the bpb or
in a diri. The dosfs_identify_partition() only returns the label in the bpb so
more usually than not it will show one name in Tracker's mount menu and a
different name when mounted.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30837 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Allow a sector size of 4096 as well; this change allows Haiku to mount an
iPod.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30159 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added a flag B_DISK_SYSTEM_SUPPORTS_WRITING to determine whether or not a
file system can write to files before mounting.
* Set the flag for all file systems that actually can write.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28055 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added FS interface hooks io() and cancel_io(). The former is supposed
to provide asynchrounous (or only synchronous, if asynchronous is not
supported) I/O request support. It will eventually replace
{read,write}_pages(). None of the FS implementations implement them
yet.
* Implemented some support functions for request-based I/O. File system
implementations can use do_fd_io() which passes an I/O request to the
layer responsible for a given FD, and do_iterative_fd_io(), which
translates a request for a file to subrequests for the underlying
device and passes them on. Both fall back to synchrounous processing
when the io() hook is not supported.
Furthermore added vfs_synchronous_io() which should be handy for the
devfs to perform io_requests synchronously for devices that don't
support the io() hook.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26655 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Unify reading the FAT volume label. One of two places didn't yet handle FAT32
volume labels at all.
* Use the common function in both identifying and mounting the volume so the
name is in sync between what the disk device manager got through scanning and
what Tracker gets through reading the fs stat.
* Strip trailing spaces from volume names in all places.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25828 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Changed recursive_lock to use a mutex instead of a semaphore.
* Adjusted code using recursive locks respectively. The initialization
cannot fail anymore, and it is possible to use recursive locks in the
early boot process (even uninitialized, if in BSS), which simplifies
things a little.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25687 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added BDiskSystem::ShortName() and everything needed to get it there.
* Added BDiskDeviceRoster::GetDiskSystem() method, that can get a disk system
by short/pretty/module name - since they should all be unique, I put them
in a single namespace, please complain if you don't like that :-)
* Cleaned up DiskSystem.h and DiskDeviceRoster.h according to the updated
header guidelines.
* Renamed ntfs pretty name from "ntfs File System" to "Windows NT File System".


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25414 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add support for detecting FAT32 volume labels.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24996 a95241bf-73f2-0310-859d-f6bbb57e9c96

Just a bit of cleanup, remove trailing whitespace mostly. No functional changes.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24995 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Ported the FAT filesystem to the recent filesystem interface changes which
was, thanks to the detailed instructions from Ingo, quite doable.
* Ported the (deprecated and now publically removed) notify_listener() calls
to the respective new notify_* calls.
* Fixed debug build.
* Added the FAT filesystem back to the image.

I only tested the filesystem briefly and everything seemed to work as expected
(mounted the FAT part of my bootable Haiku memory stick, opened a few files
and copied something to it). At least it should not be any more broken than
before the interface changes ;-).

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24987 a95241bf-73f2-0310-859d-f6bbb57e9c96

* block_cache_set_dirty() was used incorrectly; I wonder why I write any
documentation... when you ask the block cache for a writable block, it's
automatically dirty.
* This fixes bug #1330.
* Minor style cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22317 a95241bf-73f2-0310-859d-f6bbb57e9c96
