Subject: [PATCH] [fs/9p] Check for NULL fid in v9fs_dir_release()
Date: Wed, 25 Aug 2010 09:26:21 -0700 [thread overview]
Message-ID: <1282753581-28231-1-git-send-email-jvrao@linux.vnet.ibm.com> (raw)
NULL fid should be handled in cases where we endup calling v9fs_dir_release()
before even we instantiate the fid in filp.
