Subject: [PATCH v5 06/20] fsnotify: export several symbols
Date: Mon,  5 Oct 2015 07:02:28 -0400	[thread overview]
Message-ID: <1444042962-6947-7-git-send-email-jeff.layton@primarydata.com> (raw)
In-Reply-To: <1444042962-6947-1-git-send-email-jeff.layton-7I+n7zu2hftEKMMhf/gKZA@public.gmane.org>

With nfsd's new open-file caching infrastructure, we need a way to know
when unlinks occur so it can close files that it may be holding open.
fsnotify fits the bill nicely, but the symbols aren't currently exported
to modules. Export some of its symbols so nfsd can use this
infrastructure.
