Log message:
	Bugzilla 243146 (clone of bug #242720 for RHEL 4.5 z-stream):
	
	There is a race between GFS lookup code and inode cache reclaim logic that
	would create a window to allow GFS to corrupt its (GFS) inode cache. The
	occurrence is rare and only happens when gfs_inode_destroy() is invoked
	(mostly under memory pressure such that VM starts to free its inode cache
	entries). Depending on who gets the freed memory, the result can't be specified.
