Vitaliy Filippov dfb6e15eaa Implement graceful stopping of PGs 2020-04-03 13:03:42 +03:00
Vitaliy Filippov afe2e76c87 Implement regular automatic syncs, split osd_t constructor into some methods 2020-04-02 22:16:46 +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
