From c1fd7bb99637e69994d26df5f6e33192319d3866 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 12 Nov 2013 15:10:11 -0800 Subject: checkpatch: make the memory barrier test noisier Peter Zijlstra prefers that comments be required near uses of memory barriers. Change the message level for memory barrier uses from a --strict test only to a normal WARN so it's always emitted. This might produce false positives around insertions of memory barriers when a comment is outside the patch context block. And checkpatch is still stupid, it only looks for existence of any comment, not at the comment content.
