Subject: [PATCH 2/3] pNFS/flexfiles: Clean up redundant calls to pnfs_put_lseg()
Date: Mon, 22 Jun 2020 15:04:16 -0400 [thread overview]
Message-ID: <20200622190417.566077-2-trondmy@kernel.org> (raw)
In-Reply-To: <20200622190417.566077-1-trondmy@kernel.org>
From: Trond Myklebust <trond.myklebust@hammerspace.com>
Both nfs_pageio_reset_read_mds() and nfs_pageio_reset_write_mds()
do call pnfs_generic_pg_cleanup() for us.
