Hi all, this series removes the BLK_EH_HANDLED return value, and instead places responsibility of timed out commands entirely on the drivers. Except for some odd layering vilations in libiscsi this actually is surprisingly simple. Some of the grunt work here is from Keith and Bart, just repackaged up Changes since v1: - reordered the series - added back submission-time hctx lock - use cmpxchg to protect against concurrent blk_abort_request calls.
