Vitaliy Filippov 06f4978085 Fix fsync check in blockstore_flush (data fsyncs were disabled instead of journal fsyncs) 2021-03-25 02:41:58 +03:00
Vitaliy Filippov b0ad1e1e6d Remember writes as "unsynced" only after completing them 
Previously BS_OP_SYNC could take unfinished writes and add them into the journal before
they were actually completed. This was leading to crashes with the message
"BUG: Unexpected dirty_entry 2000000000001:9f2a0000 v3 unstable state during flush: 338"

Vitaliy Filippov 88671cf745 Fix a bug causing all flushers to wait for an fsync without actually trying to do it 
This happened because flusher_count became dynamic and fsync_batch() was comparing the number
of flushers currently ready to do an fsync with the maximum number of flushers. Also the number
wasn't rechecked on every loop which was also incorrect.

Now the interrupted_rebalance test passes even without IMMEDIATE_COMMIT=1.
