From 8abd053cf07a1e4264d59c671e05a602fc7a31ad Mon Sep 17 00:00:00 2001 From: Nobuhiro Iwamatsu Date: Tue, 8 Apr 2014 11:12:46 +0900 Subject: [PATCH] fs: fat: Fix cache align error message in fatwrite Use of malloc of do_fat_write() causes cache error on ARM v7 platforms. Perhaps, the same problem will occur at any other CPUs. This replaces malloc with memalign to fix cache buffer alignment.
