  Modified files:
    sys/dev/md           md.c 
  Log:
  - Conditionally acquire Giant in mdstart_vnode(), mdcreate_vnode(), and
    mddestroy() only if the file is from a non-MPSAFE VFS.
  - No longer unconditionally hold Giant in the md kthread for vnode-backed
    kthreads.
  - Improve the handling of the thread exit race when destroying an md
    device.
