Subject: [PATCH 04/10] locking/rwsem: Move rwsem internal function declarations to rwsem-xadd.h
Date: Tue, 12 Feb 2019 19:27:01 -0500 [thread overview]
Message-ID: <1550017627-14504-5-git-send-email-longman@redhat.com> (raw)
In-Reply-To: <1550017627-14504-1-git-send-email-longman@redhat.com>
We don't need to expose rwsem internal functions which are not supposed
to be called directly from other kernel code.
Signed-off-by: Waiman Long <longman@redhat.com>
