Subject: [PATCH 05/20] nfsd: move nfsd_fh_match to nfsfh.h
Date: Thu, 22 Jan 2015 12:09:51 +0100 [thread overview]
Message-ID: <1421925006-24231-6-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1421925006-24231-1-git-send-email-hch@lst.de>
The pnfs code will need it too. Also remove the nfsd_ prefix to match the
other filehandle helpers in that file.
