Some filesystems try to optimize barrier flushes by maintaining fs-specific generation counters, but if we introduce generic flush generation counter for block device filesystems may use it for fdatasync(2) optimization. Optimization should works if userspace performs mutli-threaded IO with a lot of fdatasync()
