  Log:
  MFp4: Once page is written successfully, we should clear the dirty bits.
  This fixes slow operations on mmaped files, because without this fix,
  pages were written to disk multiple times.
  
  If one is looking for even greater speed up for such operation, he should
  disable ZIL (by setting vfs.zfs.zil_disable to 1 in /boot/loader.conf).
  Disabling ZIL makes fsx run ~9 times faster.
