Vitaliy Filippov 416a80b099 Make blockstore object state a combination of type and workflow 2020-07-04 22:20:32 +03:00
Vitaliy Filippov 592bcd3699 Fix QEMU driver bugs (QEMU and qemu-img now work! hooray!) 2020-06-26 18:25:43 +03:00
Vitaliy Filippov 0f43f6d3f6 Fix crashes, print some stats
Notably:
- fix the `delete op` inside lambda callback crash (it frees the lambda itself
  which results in use-after-free with g++)
- fix stop_client() reenterability
- fix a bug in the blockstore layer which resulted in always returning version=0
  for zero-length reads
- change error codes for blockstore_stabilize
