[GIT PULL] Btrfs updates

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

Hi everyone,

The for-linus branch of the btrfs tree:

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

Has our current set of fixes.  This is fairly small, Alexandre Oliva has
been chasing problems in our block allocator and kicked out important
fixes.

Jan Schmidt fixed a merge error in the raid repair code, we're now
properly repairing failed blocks (io errors or crc errors) without
having to run a scrub.

Alexandre Oliva (5) commits (+8/-8):
    Btrfs: skip block groups without enough space for a cluster (+1/-1)
    Btrfs: start search for new cluster at the beginning (+2/-4)
    Btrfs: reset cluster's max_size when creating bitmap (+1/-0)
    Btrfs: skip allocation attempt from empty cluster (+3/-3)
    Btrfs: initialize new bitmaps' list (+1/-0)

Li Zefan (1) commits (+3/-3):
    Btrfs: fix oops when calling statfs on readonly device

Arnd Hannemann (1) commits (+2/-2):
    Fix URL of btrfs-progs git repository in docs
