From bddd2d65a48c492d3e585e65df0be89c58b4acda Mon Sep 17 00:00:00 2001 From: Lalit Chandivade Date: Fri, 3 Sep 2010 15:20:53 -0700 Subject: [PATCH] [SCSI] qla2xxx: Update to AER support, do early abort commands. Currently the IOs are returned back in slot reset, this could be late and can cause error handler to invoke. If error handler invokes, eh_abort fails and escalate to device/bus/host resets causing issues. The commands need to be returned back to upper layer in io_error_detected.
