From 373d4d099761cb1f637bed488ab3871945882273 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Mon, 21 Jan 2013 17:17:39 +1030 Subject: taint: add explicit flag to show whether lock dep is still OK. Fix up all callers as they were before, with make one change: an unsigned module taints the kernel, but doesn't turn off lockdep.
