Subject: Re: [PATCH v4] binfmt_elf.c: use get_random_int() to fix entropy
 depleting

Hi Stephan,

As per your previous comments for this fix, you have promised another approach which
is promising to avoid entropy starvation, I got this info from the following thread:
[PATCH] avoid entropy starvation due to stack protection
https://lkml.org/lkml/2012/12/14/267

My current fix has been merged into Andrew's tree(marked in "stuck" state) for a long
time, and it also works well in our internal specific kernel, I'd like to know if there
is any update from you, so that we can move it along for mainline. :)

Thanks,
-Jeff
