[GIT PULL] Btrfs updates for 2.6.30-rc

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

Hello everyone,

Here's a small btrfs update for the next rc.  The IO failure fixes help
btrfs carry on when metadata reads fail because all copies of a given
block are bad.  There is still a bunch of work to do in that area, but
this a small start that avoids hopeless looping.

Chris Mason (3) commits (+37/-6):
    Btrfs: remove some WARN_ONs in the IO failure path (+0/-3)
    Btrfs: Don't loop forever on metadata IO failures (+36/-3)
    Btrfs: init inode ordered_data_close flag properly (+1/-0)

Li Hong (1) commits (+0/-4):
    Btrfs: remove outdated comment in btrfs_ioctl_resize()

Sankar P (1) commits (+1/-1):
    Btrfs: Spelling fix in btrfs_lookup_first_block_group comments

Sage Weil (1) commits (+2/-2):
    Btrfs: make show_options result match actual option names
