Subject: [PATCH 008 of 14] knfsd: nfsd: fix misplaced fh_unlock() in nfsd_link()
Date: Tue, 27 Jun 2006 17:20:17 +1000	[thread overview]
Message-ID: <1060627072017.26685@suse.de> (raw)
In-Reply-To: 20060627171533.26405.patches@notabene


From: David M. Richter <richterd@citi.umich.edu>

In the event that lookup_one_len() fails in nfsd_link(), fh_unlock() is
skipped and locks are held overlong.

Patch was tested on 2.6.17-rc2 by causing lookup_one_len() to fail and
verifying that fh_unlock() gets called appropriately.
