Subject: Re: [PATCH] prctl: allow prctl_set_mm_exe_file without unmapping old
 exe

PS:

1. I'm not fully sure of my research here, please contradict me if there's
   some non-obvious reason to keep this check.

2. While writing this I discovered that someone else had submitted
   essentially the same patch independently about three years ago and
   gotten no reply. Hopefully this one will have better luck.
