There are cases where EXT4 is a bit too conservative sending barriers down to the disk; there are cases where the transaction in progress is not the one that sent the barrier (in other words: the fsync is for a file for which the IO happened more time ago and all data was already sent to the disk). For that case, a more performing tradeoff can be made on SSD devices (which have the ability to flush their dram caches in a hurry on a power fail event) where the barrier gets sent to the disk, but we don't need to wait for the barrier to complete. Any consecutive IO will block on the barrier correctly. Signed-off-by: Diab Neiroukh <lazerl0rd@thezest.dev> |
