Subject[RFC PATCH] proc: making "limits" world readable
Date
hi,

I'd like to have the /proc/<pid>/limits file world readable,
but I'm not sure this could cause some security issue.. thoughts?

The "limit" file was as a debug feature by following commit:
- proc: export a processes resource limits via /proc/pid
commit d85f50d5e1aa99ab082035f94265847521819e58
Author: Neil Horman <nhorman@tuxdriver.com>


thanks for any ideas,
jirka
