Log:
Code to prevent a panic caused by procfs_exit(). Note that i don't know
what is teh root cause -- but, sometimes, a procfs vnode in pfshead is
apparantly corrupt (or a UFS vnode instead). Without this patch, I can
get it to panic by doing (in csh)
while (1)
ps auxwww
end
and it will panic when the PID's wrap. With it, it does not panic.
Yes -- I know that this is NOT the right way to fix it. But I haven't
been able to get it to panic yet (which confuses me). I am going to
be looking into the vgone() code now, as that may be a part of it.
