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"
