Subject: [PATCH 07/19] exofs: use iput() for inode reference count decrements
Date: Sat, 16 Oct 2010 19:14:01 +1100 [thread overview]
Message-ID: <1287216853-17634-8-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1287216853-17634-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
Direct modification of the inode reference count is a no-no. Convert
the exofs decrements to call iput() instead of acting directly on
i_count.
