[PATCH] fix up lockdep trace in fs/exec.c
This fixes the locking error noticed by lockdep:
=============================================
[ INFO: possible recursive locking detected ]
---------------------------------------------
init/1 is trying to acquire lock:
(&sighand->siglock){....}, at: [<c047a78a>] flush_old_exec+0x3ae/0x859
but task is already holding lock:
(&sighand->siglock){....}, at: [<c047a77a>] flush_old_exec+0x39e/0x859
other info that might help us debug this:
2 locks held by init/1:
#0: (tasklist_lock){..--}, at: [<c047a76a>] flush_old_exec+0x38e/0x859
#1: (&sighand->siglock){....}, at: [<c047a77a>] flush_old_exec+0x39e/0x859
