+From fffecea36f26cf21d4a7cf38d0697fe841d6a84f Mon Sep 17 00:00:00 2001

+Subject: [PATCH 27/96] compiler.h: only include asm/rwonce.h for kernel code
+
+This header file is not in uapi, which makes any user space code that includes
+linux/compiler.h to fail with the error 'asm/rwonce.h: No such file or directory'
+
+Fixes: e506ea451254 ("compiler.h: Split {READ,WRITE}_ONCE definitions out into rwonce.h")
