From 18e9cea74951b64282964f9625db94c5d5a007bd Mon Sep 17 00:00:00 2001 From: Greg Price Date: Fri, 29 Nov 2013 14:59:45 -0500 Subject: [PATCH] random: fix description of get_random_bytes After this remark was written, commit d2e7c96af added a use of arch_get_random_long() inside the get_random_bytes codepath. The main point stands, but it needs to be reworded.
