[PATCH 08/14] null_blk: complete requests from ->timeout

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



By completing the request entirely in the driver we can remove the
BLK_EH_HANDLED return value and thus the split responsibility between the
driver and the block layer that has been causing trouble.
