Merge branch 'for-linus' of git://oss.sgi.com:8090/xfs/xfs-2.6
* 'for-linus' of git://oss.sgi.com:8090/xfs/xfs-2.6: (59 commits) [XFS] eagerly remove vmap mappings to avoid upsetting Xen [XFS] simplify validata_fields [XFS] no longer using io_vnode, as was remaining from 23 cherrypick [XFS] Remove STATIC which was missing from prior manual merge [XFS] Put back the QUEUE_ORDERED_NONE test in the barrier check. [XFS] Turn off XBF_ASYNC flag before re-reading superblock. [XFS] avoid race in sync_inodes() that can fail to write out all dirty data [XFS] This fix prevents bulkstat from spinning in an infinite loop. [XFS] simplify xfs_create/mknod/symlink prototype [XFS] avoid xfs_getattr in XFS_IOC_FSGETXATTR ioctl [XFS] get_bulkall() could return incorrect inode state [XFS] Kill unused IOMAP_EOF flag [XFS] fix when DMAPI mount option processing happens [XFS] ensure file size is logged on synchronous writes [XFS] growlock should be a mutex [XFS] replace some large xfs_log_priv.h macros by proper functions [XFS] kill struct bhv_vfs [XFS] move syncing related members from struct bhv_vfs to struct xfs_mount [XFS] kill the vfs_flags member in struct bhv_vfs [XFS] kill the vfs_fsid and vfs_altfsid members in struct bhv_vfs ...
