Subject: [PATCH AUTOSEL 5.8 29/53] nvme: have nvme_wait_freeze_timeout return if it timed out
Date: Mon, 7 Sep 2020 12:31:55 -0400 [thread overview]
Message-ID: <20200907163220.1280412-29-sashal@kernel.org> (raw)
In-Reply-To: <20200907163220.1280412-1-sashal@kernel.org>
From: Sagi Grimberg <sagi@grimberg.me>
[ Upstream commit 7cf0d7c0f3c3b0203aaf81c1bc884924d8fdb9bd ]
Users can detect if the wait has completed or not and take appropriate
actions based on this information (e.g. weather to continue
initialization or rather fail and schedule another initialization
attempt).
