From 7cf0d7c0f3c3b0203aaf81c1bc884924d8fdb9bd Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Thu, 30 Jul 2020 13:24:45 -0700 Subject: [PATCH] nvme: have nvme_wait_freeze_timeout return if it timed out 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).
