From 50e8a2890ed0eeb7a11ae0c39144fcdd1cad1cf8 Mon Sep 17 00:00:00 2001 From: Marcin Slusarz Date: Fri, 8 Feb 2008 04:20:13 -0800 Subject: [PATCH] ext3: replace all adds to little endians variables with le*_add_cpu replace all: little_endian_variable = cpu_to_leX(leX_to_cpu(little_endian_variable) + expression_in_cpu_byteorder); with: leX_add_cpu(&little_endian_variable, expression_in_cpu_byteorder); sparse didn't generate any new warning with this patch Signed-off-by: Marcin Slusarz Cc: Mark Fasheh Cc: David Chinner Cc: Timothy Shimmin Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/ext3/balloc.c | 7 ++----- fs/ext3/ialloc.c | 12 ++++-------- fs/ext3/resize.c | 12 ++++-------- fs/ext3/super.c | 2 +- fs/ext3/xattr.c | 6 ++---- 5 files changed, 13 insertions(+), 26 deletions(-) diff --git a/fs/ext3/balloc.c b/fs/ext3/balloc.c index a7571303110..da0cb2c0e43 100644 --- a/fs/ext3/balloc.c +++ b/fs/ext3/balloc.c @@ -630,9 +630,7 @@ do_more: jbd_unlock_bh_state(bitmap_bh);
