Subject: [PATCH] [SCSI] Enable retries for SYNCRONIZE_CACHE commands to fix I/O error
Some arrays are giving I/O errors with ext3 filesystems when
SYNCHRONIZE_CACHE gets a UNIT_ATTENTION. What is happening is that
these commands have no retries, so the UNIT_ATTENTION causes the
barrier to fail. We should be enable retries here to clear any
transient error and allow the barrier to succeed.
