Subject: [PATCH v6 05/14] ceph-fs: replace direct access of d_count with the d_count() helper
Date: Mon,  8 Jul 2013 21:09:55 -0400	[thread overview]
Message-ID: <1373332204-10379-6-git-send-email-Waiman.Long@hp.com> (raw)
In-Reply-To: <1373332204-10379-1-git-send-email-Waiman.Long@hp.com>

All readonly references to d_count outside of the core dcache code
should be changed to use the new d_count() helper as they shouldn't
access its value directly.  There is no change in logic and everything
should just work.
