Subject: [PATCH] export xattr_resolve_name_sns [1/4]
Date: Fri, 22 Jun 2007 20:25:26 +0200 [thread overview]
Message-ID: <11825367292921-git-send-email-arw@arw.name> (raw)
In-Reply-To: <20070621155516.GA6838@faui01.informatik.uni-erlangen.de>
From: Johannes Schlumberger <spjsschl@cip.informatik.uni-erlangen.de>
Makes it possible to get extended attributes for a given inode. We need this
for cases where we no longer have the corresponding direntry.
