The scsi_eh thread responds to KILL INT and TERM so that the module can
be unloaded - however I cant see a reason why you would want it to
respond to any signals when it is built into the kernel. Currently you
get a zombie thread if it is built in and receives such a signal.
This trivial diff (2.2.x) seems like the right thing to do unless
I'm overlooking something. It solves the zombie problem anyways.
The code in 2.3.x looks unchanged so it probably needs it too.
Paul.
