From 710bc78f829d014eca95ed7ccc4052bc064b1320 Mon Sep 17 00:00:00 2001 From: Quinn Tran Date: Wed, 26 Sep 2018 22:05:16 -0700 Subject: [PATCH] scsi: qla2xxx: Fix recursive mailbox timeout This patch prevents user space mailbox request from doing chip reset if the mailbox timed out. The chip reset is only reserved for the DPC thread to ensure all mailbox requests are flushed properly. The DPC thread is responsible for the flushing all MBs and chip reset.
