Subject: [PATCH 3/3] pNFS/flexfiles: The mirror count could depend on the layout segment range
Date: Mon, 22 Jun 2020 15:04:17 -0400 [thread overview]
Message-ID: <20200622190417.566077-3-trondmy@kernel.org> (raw)
In-Reply-To: <20200622190417.566077-2-trondmy@kernel.org>
From: Trond Myklebust <trond.myklebust@hammerspace.com>
Make sure we specify the layout segment range when calculating the
mirror count. In theory, that number could depend on the range to
which we're writing.
