From 2ce88dd04276839002a3b31161090d282316610b Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Tue, 30 Apr 2013 10:43:10 -0400 Subject: audit: do not needlessly take a spinlock in copy_signal current->signal->audit_* can only change from a netlink message from current. Obviously in this case we cannot be handling a netlink message from current. So there is no change these can change under us. No need to take a lock to read them.
