-Subject: [PATCH] ubifs: Use dirty_writeback_interval value for wbuf timer
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Right now wbuf timer has hardcoded timeouts and there is no place for
-manual adjustments. Some projects / cases many need that though. Few
-file systems allow doing that by respecting dirty_writeback_interval
-that can be set using sysctl (dirty_writeback_centisecs).
-
-Lowering dirty_writeback_interval could be some way of dealing with user
-space apps lacking proper fsyncs. This is definitely *not* a perfect
-solution but we don't have ideal (user space) world. There were already
-advanced discussions on this matter, mostly when ext4 was introduced and
-it wasn't behaving as ext3. Anyway, the final decision was to add some
-hacks to the ext4, as trying to fix whole user space or adding new API
-was pointless.
-
-We can't (and shouldn't?) just follow ext4. We can't e.g. sync on close
-as this would cause too many commits and flash wearing. On the other
-hand we still should allow some trade-off between -o sync and default
-wbuf timeout. Respecting dirty_writeback_interval should allow some sane
-cutomizations if used warily.
