Subject: [EXT] [PATCH 4.19 60/66] scsi: qla2xxx: Fix device staying in blocked
state
External Email
----------------------------------------------------------------------
From: Quinn Tran <qt...@marvell.com>
commit 2137490f2147a8d0799b72b9a1023efb012d40c7 upstream.
This patch fixes issue reported by some of the customers, who discovered that
after cable pull scenario the devices disappear and path seems to remain in
blocked state. Once the device reappears, driver does not seem to update path
to online. This issue appears because of the defer flag creating race condition
where the same session reappears. This patch fixes this issue by indicating
SCSI-ML of device lost when
qlt_free_session_done() is called from qlt_unreg_sess().
Fixes: 41dc529a4602a ("qla2xxx: Improve RSCN handling in driver")
