From 146aa1786d4978795cab5347d810e00236dea1c3 Mon Sep 17 00:00:00 2001 From: Raghava Aditya Renukunta Date: Thu, 16 Feb 2017 12:51:20 -0800 Subject: [PATCH] scsi: aacraid: Skip IOP reset on controller panic(SMART Family) When the SMART family of controller panic (KERNEL_PANIC) , they do not honor IOP resets. So better to skip it and directly perform a IWBR reset. Signed-off-by: Raghava Aditya Renukunta Reviewed-by: David Carroll Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K.
