From bd29e568a4cb6465f6e5ec7c1c1f3ae7d99cbec1 Mon Sep 17 00:00:00 2001 From: "Luck, Tony" Date: Wed, 16 Nov 2011 10:50:56 -0800 Subject: [PATCH] fix typo/thinko in get_random_bytes() If there is an architecture-specific random number generator we use it to acquire randomness one "long" at a time. We should put these random words into consecutive words in the result buffer - not just overwrite the first word again and again. Signed-off-by: Tony Luck Acked-by: H.
