I found that VolumeDirty keeps VOL_DIRTY until sync or umount regardless of sync or dirsync enabled,
because there is no paired call to exfat_set_volume_dirty()/exfat_clear_volume_dirty() in __exfat_write_inode().
If exfat_set_volume_dirty()/exfat_clear_volume_dirty() is called in pairs in __exfat_write_inode(),
it will cause frequent writing of bootsector.
So, how about removing exfat_clear_volume_dirty() from each operations, except in exfat_sync_fs()?
