[PATCH] i2o: block IO errors on i2o disk
I2O subsystem has been broken in mainstream several months ago (after 2.6.18). Commit 4aff5e2333c9a1609662f2091f55c3f6fffdad36 from Jens Axboe split struct request ->flags into two parts: cmd_type and cmd_flags. In i2o layer this patch has replaced flag REQ_SPECIAL by the according cmd_type. However i2o has used REQ_SPECIAL not as command type but as driver-specific flag for the debug purposes. As result all i2o requests have type "special" now, are not processed to the hardware and fail with I/O error: i2o/hda:<3>Buffer I/O error on device i2o/hda, logical block 0 Buffer I/O error on device i2o/hda, logical block 0 Buffer I/O error on device i2o/hda, logical block 0 unable to read partition table block-osm: device added (TID: 207): i2o/hda The following patch removes the extra debug checks without any drawbacks and restores the normal driver's work.
