Vitaliy Filippov c22e096943 Output journal offsets in debug trace in hex, add detailed "still waiting" messages 2020-06-01 16:18:19 +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

Vitaliy Filippov 2b09710d6f Implement blockstore rollback operation
Rollback operation is required for the primary OSD to kill unstable
object versions in OSD peers so they don't occupy journal space

Vitaliy Filippov a3d3949dce Do not overwrite same journal sector multiple times
It doesn't reduce actual WA, but it reduces tail latency (Q=32, 10% / 50% / 90% / 99% / 99.95%):
- write: 766us/979us/1090us/1303us/1729us vs 1074us/1450us/2212us/3261us/4113us
- sync: 701us/881us/1188us/1762us/2540us vs 269us/955us/1663us/2638us/4146us
