Subject: [PATCH 3/4] pNFS: Clean up pnfs_layoutreturn_free_lsegs()
Date: Tue,  5 Jan 2021 10:26:19 -0500
Message-ID: <20210105152620.754453-3-trondmy@kernel.org> (raw)
In-Reply-To: <20210105152620.754453-2-trondmy@kernel.org>

From: Trond Myklebust <trond.myklebust@hammerspace.com>

Remove the check for whether or not the stateid is NULL, and fix up the
callers.
