MN10300: Call update_process_times() outside of the xtime_lock
Call update_process_times() outside of the xtime_lock. Somewhere somewhere inside one of the functions called by that, xtime_lock is readlocked, which ends up in a deadlock situation. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
