Subject: [PATCH AUTOSEL 5.2 47/94] pNFS/flexfiles: Don't time out requests on hard mounts
Date: Wed,  4 Sep 2019 11:56:52 -0400
Message-ID: <20190904155739.2816-47-sashal@kernel.org> (raw)
In-Reply-To: <20190904155739.2816-1-sashal@kernel.org>

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

[ Upstream commit 7af46292dadcf8870946916f79fdddf79bd7267f ]

If the mount is hard, we should ignore the 'io_maxretrans' module
parameter so that we always keep retrying.
