Revision 671d40f4aa20d31121695e33393c9bd87053f4fa authored by Alexey Dobriyan on 23 April 2007, 21:41:07 UTC, committed by Linus Torvalds on 24 April 2007, 15:23:08 UTC
pcd_lock and pf_spin_lock are passed to blk_init_queue() which, seeing them as valid lock pointer, sets it as ->queue_lock. The problem is that pcd_lock and pf_spin_lock aren't initialized anywhere.
