Pull GFS2 updates from Steven Whitehouse: "There is not a whole lot of change this time - there are some further changes which are in the works, but those will be held over until next time. Here there are some clean ups to inode creation, the addition of an origin (local or remote) indicator to glock demote requests, removal of one of the remaining GFP_NOFAIL allocations during log flushes, one minor clean up, and a one liner bug fix." * git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw: GFS2: Flush work queue before clearing glock hash tables GFS2: Add origin indicator to glock demote tracing GFS2: Add origin indicator to glock callbacks GFS2: replace gfs2_ail structure with gfs2_trans GFS2: Remove vestigial parameter ip from function rs_deltree GFS2: Use gfs2_dinode_out() in the inode create path GFS2: Remove gfs2_refresh_inode from inode creation path GFS2: Clean up inode creation path
