... by checking that previous block is fully written and flushed. It allows to skip commit delays since we can give up on aggregation in that case. This removes zil_min_commit_timeout parameter, since for single-threaded workloads it is not needed at all, while on very fast devices even some multi-threaded workloads may get detected as single-threaded and still bypass the wait. To give multi-threaded workloads more aggregation chances increase zfs_commit_timeout_pct from 5 to 10%, as they should suffer less from additional latency. Also single-threaded workloads detection allows in perspective better prediction of the next block size.
