Merge tag 'for-linus-v3.10-rc1' of git://oss.sgi.com/xfs/xfs

Pull xfs update from Ben Myers:
 "For 3.10-rc1 we have a number of bug fixes and cleanups and a
  currently experimental feature from David Chinner, CRCs protection for
  metadata.  CRCs are enabled by using mkfs.xfs to create a filesystem
  with the feature bits set.

   - numerous fixes for speculative preallocation
   - don't verify buffers on IO errors
   - rename of random32 to prandom32
   - refactoring/rearrangement in xfs_bmap.c
   - removal of unused m_inode_shrink in struct xfs_mount
   - fix error handling of xfs_bufs and readahead
   - quota driven preallocation throttling
   - fix WARN_ON in xfs_vm_releasepage
   - add ratelimited printk for different alert levels
   - fix spurious forced shutdowns due to freed Extent Free Intents
   - remove some obsolete XLOG_CIL_HARD_SPACE_LIMIT() macros
   - remove some obsoleted comments
   - (experimental) CRC support for metadata"
