From: Akira Yokosawa Date: Fri, 15 Jan 2021 15:11:45 +0000 (+0900) Subject: rculist: Replace reference to atomic_ops.rst X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5bb1369d4bea078dd1298dfc2c6ce781d9e34dde;p=linux.git rculist: Replace reference to atomic_ops.rst The hlist_nulls_for_each_entry_rcu() docbook header references the atomic_ops.rst file, which was removed in commit f0400a77ebdc ("atomic: Delete obsolete documentation"). This commit therefore substitutes a section in memory-barriers.txt discussing the use of barrier() in loops. Cc: Peter Zijlstra Signed-off-by: Akira Yokosawa Signed-off-by: Paul E.
