Re: [PATCH v2] exfat: do not clear VolumeDirty in writeback

Hi, Yuezhang,Mo

I think it's good.
It will not be possible to clear dirty automatically, but I think device life and reliable integrity are more important.

Use __sync_dirty_buffer() with REQ_FUA/REQ_PREFLUSH instead to guarantee a strict write order (including devices).
