Steven Whitehouse 363275216c [GFS2] Reordering in deallocation to avoid recursive locking ... Despite my earlier careful search, there was a recursive lock left in the deallocation code. This removes it. It also should speed up deallocation be reducing the number of locking operations which take place by using two "try lock" operations on the two locks involved in inode deallocation which allows us to grab the locks out of order (compared with NFS which grabs the inode lock first and the iopen lock later). It is ok for us to fail while doing this since if it does fail it means that someone else is still using the inode and thus it wouldn't be possible to deallocate anyway. This fixes the bug reported to me by Rob Kenna. Cc: Rob Kenna <rkenna@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>		2006-04-28 10:46:21 -04:00
