[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.
