    sys/sys              signal.h 
    sys/kern             vfs_aio.c 
  Log:
  Check validity of signal callback requested via aio routines.
  
  Also move the insertion of the request to after the request is validated,
  there's still looks like there may be some problems if an invalid address
  is passed to the aio routines, basically a possible leak or having a
  not completely initialized structure on the queue may still be possible.
  
  A new sig macro was made _SIG_VALID to check the validity of a signal,
  it would be advisable to use it from now on (in kern/kern_sig.c) rather
  than rolling your own.
