From 1d5b897706d11ac59fecd85ba7b1cbf91c44fe50 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 14 Apr 2015 15:43:52 -0700 Subject: ocfs2: make mlog_errno return the errno ocfs2 does mlog_errno(v); return v; in many places. Change mlog_errno() so we can do return mlog_errno(v); For some weird reason this patch reduces the size of ocfs2 by 6k: akpm3:/usr/src/25> size fs/ocfs2/ocfs2.ko text data bss dec hex filename 1146613 82767 832192 2061572 1f7504 fs/ocfs2/ocfs2.ko-before 1140857 82767 832192 2055816 1f5e88 fs/ocfs2/ocfs2.ko-after [dan.carpenter@oracle.com: double evaluation concerns in mlog_errno()] Cc: Mark Fasheh Cc: Joel Becker Cc: alex chen Signed-off-by: Dan Carpenter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/ocfs2/cluster/masklog.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'fs') diff --git a/fs/ocfs2/cluster/masklog.h b/fs/ocfs2/cluster/masklog.h index 2260fb9e6508..7fdc25a4d8c0 100644 --- a/fs/ocfs2/cluster/masklog.h +++ b/fs/ocfs2/cluster/masklog.h @@ -196,13 +196,14 @@ extern struct mlog_bits mlog_and_bits, mlog_not_bits; } \ } while (0) -#define mlog_errno(st) do { \ +#define mlog_errno(st) ({ \ int _st = (st); \ if (_st != -ERESTARTSYS && _st != -EINTR && \ _st != AOP_TRUNCATED_PAGE && _st != -ENOSPC && \ _st != -EDQUOT) \ mlog(ML_ERROR, "status = %lld\n", (long long)_st); \ -} while (0) + _st; \ +}) #define mlog_bug_on_msg(cond, fmt, args...) do { \ if (cond) { \ -- cgit v1.2.3-59-g8ed1b
