[PATCH] kcsan: Prefer '__no_kcsan inline' in test

From: Marco Elver
Date: Tue Jun 02 2020 - 10:36:49 EST


Instead of __no_kcsan_or_inline, prefer '__no_kcsan inline' in test --
this is in case we decide to remove __no_kcsan_or_inline.

Hi Paul,

This is to prepare eventual removal of __no_kcsan_or_inline, and avoid a
series that doesn't apply to anything other than -next (because some
bits are in -tip and the test only in -rcu; although this problem might
be solved in 2 weeks). This patch is to make sure in case the
__kcsan_or_inline series is based on -tip, integration in -next doesn't
cause problems.

This came up in
https://lkml.kernel.org/r/20200529185923.GO706495@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Thanks,
-- Marco
