Well here is the comments in mm/vmscan.c

/*
* Hey, if somebody wants to kill us, be our guest.
* Don't come running to mama if things don't work.
*/
siginitsetinv(&current->blocked, sigmask(SIGKILL));

So basically a word of advice...if you don't want it dead
don't be killing it...I guess there could be reasons as
to why you'd want to kill kswapd. I can't think of any
though. I guess if you want to defeat this "feature"
Just #if 0 out the siginitsetinv line in mm/vmscan.c
