Subject: [PATCH] fs, proc: add help for CONFIG_PROC_CHILDREN
Date: Wed,  8 Jul 2015 22:28:04 +0200	[thread overview]
Message-ID: <1436387284-3998-1-git-send-email-iago@endocode.com> (raw)

The purpose of the option was documented in
Documentation/filesystems/proc.txt but the help text was missing.

Add small help text that also points to the documentation.
