Should be a final remaining fix to EC + non-capacitor (non-immediate-commit) write hangs :).
First it was breaking non-EC ("instantly stable") writes because they sometimes
complete out of order which was leading to the following error:
terminate called after throwing an instance of 'std::runtime_error'
what(): BUG: Unexpected dirty_entry 1000000000001:29480000 v65540 unstable state during flush: 0x151
But it is easily fixed by scanning previous and next dirty_entries in mark_stable.
Slightly reduces WA. For example, in 4K T1Q128 replicated randwrite tests
WA is reduced from ~3.6 to ~3.1, in T1Q64 from ~3.8 to ~3.4.
Only effective without no_same_sector_overwrites.
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"
Make syncs wait for all previous writes because it's the only way
to make sure that OSDs do not receive incomplete writes in LIST results
during peering when some writes are still in progress.
Also simplify blockstore submission queue logic.
