Pull misc udf, ext2, ext3, and isofs fixes from Jan Kara:
 "Assorted, mostly trivial, fixes for udf, ext2, ext3, and isofs.  I'm
  on vacation and scarcely checking email since we are expecting baby
  any day now but these fixes should be safe to go in and I don't want
  to delay them unnecessarily."

  udf: avoid info leak on export

don't pass nameidata to ->create()

2012-07-14T12:34:47+00:00

boolean "does it have to be exclusive?" flag is passed instead;
Local filesystem should just ignore it - the object is guaranteed
not to be there yet.

stop passing nameidata to ->lookup()

2012-07-14T12:34:32+00:00

Just the flags; only NFS cares even about that, but there are
legitimate uses for such argument.  And getting rid of that
completely would require splitting ->lookup() into a couple
of methods (at least), so let's leave that alone for now...

udf: avoid info leak on export

2012-07-13T09:21:21+00:00

For type 0x51 the udf.parent_partref member in struct fid gets copied
uninitialized to userland. Fix this by initializing it to 0.

udf: Improve table length check to avoid possible overflow

2012-07-10T16:02:17+00:00

When a partition table length is corrupted to be close to 1 << 32, the
check for its length may overflow on 32-bit systems and we will think
the length is valid. Later on the kernel can crash trying to read beyond
end of buffer. Fix the check to avoid possible overflow.

udf: Do not decrement i_blocks when freeing indirect extent block

2012-07-09T11:24:21+00:00

Indirect extent block is not accounted in i_blocks during allocation
thus we should not decrement i_blocks when we are freeing such block
during truncation.

udf: Fix memory leak when mounting

2012-07-09T10:03:12+00:00

When we are mounting filesystem, we can load one partition table before
finding out that we cannot complete processing of logical volume descriptor
and trying the reserve descriptor. Free the table properly before trying
the reserve descriptor.

UDF: Remove unnecessary variable "offset" from udf_fill_inode

2012-07-09T10:03:12+00:00

The variable "offset" is not needed. Remove it.

udf: stop using s_dirt

2012-07-09T10:03:11+00:00

The UDF file-system does not need the 's_dirt' superblock flag because it does
not define the 'write_super()' method. This flag was set to 1 in few places and
set to 0 in '->sync_fs()' and was basically useless. Stop using it because it
is on its way out.

Pull UDF fixes from Jan Kara:
 "Make UDF more robust in presence of corrupted filesystem"

* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
  udf: Fortify loading of sparing table
  udf: Avoid run away loop when partition table length is corrupted
  udf: Use 'ret' instead of abusing 'i' in udf_load_logicalvol()
