Log message:
	Bugzilla 199984: Increasing gt_statfs_slots tunable could significantly
	boost gfs "df" performance; e.g. set it to 128 from current default (64)
	could cut the "df" wall time in half with larger filesystem size. However,
	the kmalloc call within stat_gfs_async() has the possibility to fail due
	to increased gt_statfs_slots. There is really no need for this array to
	be on a piece of contiguous memory. Switch to vmalloc().
