Subject: [PATCH 17/19] xfs: scrub extended attributes
Date: Fri, 10 Mar 2017 15:21:35 -0800
Message-ID: <148918809583.6959.3381046092831629536.stgit@birch.djwong.org> (raw)
In-Reply-To: <148918798893.6959.7972227235163150709.stgit@birch.djwong.org>

From: Darrick J. Wong <darrick.wong@oracle.com>

Scrub the hash tree, keys, and values in an extended attribute structure.
Refactor the attribute code to use the transaction if the caller supplied
one to avoid buffer deadocks.
