growfs

  ~ Makefile                              

  > remove -Wall (millert@)

  > correct a typo in an error message.
  > use realpath(3) to sanitize the path we're going to
  > work with, prevents silly errors when passing ncheck_ffs
  > paths from the shell with a trailing '/' since that
  > doesnt match the entry in fstab.

dev

  ~ audio.c                               

  > give the user what they expect instead of what we're working with
  > by taking into account expansion we may have done in cases such as
  > playing monoaural media on a device that only plays stereo, like
  > auich(4). (jakemsr@)

  ~ audio.c                               

  > take into account possible expansion and be more careful not to
  > try to go past the end of the buffer.
  > this and the last commit allow ffplay and gnash to work properly
  > on devices that may need to do mono to stereo conversion, like
  > auich(4).
  > problem reported by and much debugging deanna@ (jakemsr@)

  ~ ac97.c

  > defined. (jakemsr@)

kern

  ~ vfs_bio.c

sys

  ~ mbuf.h

  > _MEXTREMOVE macro which was only used by MFREE.
  > OK markus@ long time ago (claudio@)
