From 433582093a9dc5454ba03b4a7ea201d85e6aa4de Mon Sep 17 00:00:00 2001 From: Matt Mackall Date: Tue, 29 Apr 2008 01:03:01 -0700 Subject: [PATCH] random: remove cacheline alignment for locks Earlier changes greatly reduce the number of times we grab the lock per output byte, so we shouldn't need this particular hack any more.
