[GIT PULL] Btrfs fixes

[Chris Mason <chris.mason@oracle.com>]

Hi everyone,

The for-linus branch in the btrfs git repo has some fixes:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus

The big ones here are a memory leak we introduced in rc1, and 
a scheduling while atomic if the transid on disk doesn't match the
transid we expected.  This happens for corrupt blocks, or out of date
disks.

It also fixes up the ioctl definition for our ioctl to resolve logical
inode numbers.  The __u32 was a merging error and doesn't match what we
ship in the progs.
