GFS2: don't reference inode's glock during block allocation trace
Bob Peterson [Fri, 16 Nov 2012 14:04:16 +0000 (09:04 -0500)]
This patch changes the block allocation trace so that it references
the rgd's glock rather than the inode's glock. Now that the order
of inode creation is switched, this prevents a reference to the
glock which may not be set yet.
