From 7cfa95893cbb1a7615385b2b66effc754aae9e6e Mon Sep 17 00:00:00 2001 From: Prasad B Munirathnam Date: Tue, 12 Dec 2017 11:40:10 -0800 Subject: [PATCH] scsi: aacraid: Fix I/O drop during reset [ Upstream commit 5771cfffdffe709ae9b403b6f80438ca40bf850e ] "FIB_CONTEXT_FLAG_TIMEDOUT" flag is set in aac_eh_abort to indicate command timeout. Using the same flag in reset handler causes the command to time out and the I/Os were dropped. Define a new flag "FIB_CONTEXT_FLAG_EH_RESET" to make sure I/O is properly handled in eh_reset handler.
