Patch 1 is a fix. Patches 2-7 are cleanups mainly dealing with issue_flags conversions, misundertsandings of the flags and of the tw state. It'd be great to have even without even w/o the rest. 8-11 mandate ctx locking for task_work and finally removes the CQE caches, instead we post directly into the CQ. Note that the cache is used by multishot auxiliary completions. The nvme cmd change is tested with io_uring_passthrough.c, however it doesn't seem there is anything in liburing exercising ublk paths. How do we test it? It'd be great to have at least some basic tests for it.
