X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b5482a06593c851028b5dc061f9c8882bcc20008;p=linux.git rcu: Fix init_rcu_head() comment. The current (and implicit) comment header for init_rcu_head() and destroy_rcu_head() incorrectly says that they are not needed for statically allocated rcu_head structures. This commit therefore fixes this comment. Reported-by: Bart Van Assche Signed-off-by: Paul E.
