- Fix a bug introduced in 2.2.0 - pg_locks weren't disabled for pools without local_reads
correctly which could lead to inactive pools during various operations
- Fix an old bug where OSDs could send sub-operations to incorrect peer OSDs when their
connections were stopped and reestablished quickly, in 2.2.0 it was usually leading
to "sequencing broken" messages in OSD logs
- Fix debug use_sync_send_recv mode
