[PATCH] proc: Remove useless BKL in proc_pid_readlink
We already call everything except do_proc_readlink outside of the BKL in proc_pid_followlink, and there appears to be nothing in do_proc_readlink that needs any special protection. So remove this leftover from one of the BKL cleanup efforts. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
