From 01b4ff58f72dbee926077d9afa0650f6e685e866 Mon Sep 17 00:00:00 2001 From: Marco Elver Date: Tue, 31 Mar 2020 21:32:32 +0200 Subject: [PATCH] kcsan: Move kcsan_{disable,enable}_current() to kcsan-checks.h Both affect access checks, and should therefore be in kcsan-checks.h. This is in preparation to use these in compiler.h. Acked-by: Will Deacon Signed-off-by: Marco Elver Signed-off-by: Paul E.
