That was introduced by commit 77a4229719e511a0d38d9c355317ae1469adeb54 [SCSI] Retry commands with UNIT_ATTENTION sense codes to fix ext3/ext4 I/O error which just went in this May. Given that we now send barriers and discards as FS requests I think it should be reverted, preferably already during this cycle, in which the patches to send these requests as FS type were added. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
