From dadd1105ca9a1e506c678e8e410e9623efdda821 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Mon, 30 Jul 2012 02:10:44 -0600 Subject: Btrfs: fix some endian bugs handling the root times "trans->transid" is cpu endian but we want to store the data as little endian. "item->ctime.nsec" is only 32 bits, not 64.
