Subject: [PATCH 11/14] hfsplus: protect readdir against removals from open_dir_list
Date: Fri, 1 Oct 2010 09:27:15 +0200 [thread overview]
Message-ID: <20101001072715.GK27055@lst.de> (raw)
In-Reply-To: <20101001072500.GA26972@lst.de>
We already have i_mutex for readdir and the namespace operations that add
entries to open_dir_list, the only thing that was missing was the removal
in hfsplus_dir_release.
