    sys/sys              filedesc.h 
    sys/kern             kern_descrip.c vfs_syscalls.c 
  Log:
  MFC rev. 1.309 of sys/kern/kern_descrip.c,
      rev. 1.438 of sys/kern/vfs_syscalls.c,
      rev. 1.77 of sys/sys/filedesc.h:
  Mark the filedescriptor table entries with VOP_OPEN being performed for them
  as UF_OPENING. Disable closing of that entries. This should fix the crashes
  caused by devfs_open() (and fifo_open()) dereferencing struct file * by
  index, while the filedescriptor is closed by parallel thread.
