From fd07383b6bbc1418b1bdd5f295d13e600222fffa Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 31 Jul 2012 16:42:40 -0700 Subject: [PATCH] mm/memblock.c:memblock_double_array(): cosmetic cleanups This function is an 80-column eyesore, quite unnecessarily. Clean that up, and use standard comment layout style.
