From: Frederic Weisbecker Date: Sun, 4 Apr 2021 21:58:43 +0000 (+0200) Subject: doc: Fix diagram references in memory-ordering document X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=58d0db869d7ab8ca97b521f167022caa2c42cbe7;p=linux.git doc: Fix diagram references in memory-ordering document The three diagrams describing rcu_gp_init() all spuriously refer to the same figure, probably due to a copy/paste issue. This commit fixes these references. Signed-off-by: Frederic Weisbecker Signed-off-by: Paul E.
