Subject: [PATCH 01/18] libsas: cleanup spurious calls to scsi_schedule_eh
Date: Sun, 06 May 2012 11:18:02 -0700	[thread overview]
Message-ID: <20120506181802.17912.33174.stgit@dwillia2-linux.jf.intel.com> (raw)
In-Reply-To: <20120506181611.17912.3798.stgit@dwillia2-linux.jf.intel.com>

From: Maciej Trela <maciej.trela@intel.com>

eh is woken up automatically by the presence of failed commands,
scsi_schedule_eh is reserved for cases where there are no failed
commands.  This guarantees that host_eh_sceduled is only incremented
when an explicit eh request is made.
