Subject: [PATCH 22/22] pNFS/flexfiles: Specify the layout segment range in LAYOUTGET
Date: Tue, 24 Mar 2020 19:47:28 -0400 [thread overview]
Message-ID: <20200324234728.8997-23-trondmy@kernel.org> (raw)
In-Reply-To: <20200324234728.8997-22-trondmy@kernel.org>
From: Trond Myklebust <trond.myklebust@hammerspace.com>
Move from requesting only full file layout segments, to requesting
layout segments that match our I/O size. This means the server is
still free to return a full file layout, but we will no longer
error out if it does not.
