[PATCH] remove redundant lock_kernel

From: David C. Hansen (haveblue@us.ibm.com)

In fs/proc/proc_misc.c:locks_read_proc(), the BKL is grabbed while calling get_locks_status(). But, this function holds the BKL for all of its list operations already. I know that the BKL can be held recursively, but I don't see any need for this extra lock. Patch against 2.5.1 attached.
