  Modified:    sys/msdosfs  msdosfs_vnops.c
  Log:
  Don't synchronously update the directory entry at the end of every
  successful write.  Only do it for the IO_SYNC case (like ufs).  On
  one of my systems, this speeds up `iozone 24 512' from 32K/sec
  (1/128 as fast as ufs) to 2.8MB/sec (7/10 as fast as ufs).
