Subject: [PATCH v9 19/24] xfs: Simplify xfs_attr_leaf_addname
Date: Thu, 30 Apr 2020 15:50:11 -0700 [thread overview]
Message-ID: <20200430225016.4287-20-allison.henderson@oracle.com> (raw)
In-Reply-To: <20200430225016.4287-1-allison.henderson@oracle.com>
Quick patch to unnest the rename logic in the leaf code path. This will
help simplify delayed attr logic later.
