Merge git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw
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: 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
