From 2c11619a590e13fecc801c9c50859cba29740f38 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Mon, 28 Apr 2008 02:16:02 -0700 Subject: fs/ext2: use BUG_ON if (...) BUG(); should be replaced with BUG_ON(...) when the test has no side-effects to allow a definition of BUG_ON that drops the code completely. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // @ disable unlikely @ expression E,f; @@ ( if (<... f(...) ...>) { BUG(); } | - if (unlikely(E)) { BUG(); } + BUG_ON(E); ) @@ expression E,f; @@ ( if (<... f(...) ...>) { BUG(); } | - if (E) { BUG(); } + BUG_ON(E); ) // Signed-off-by: Julia Lawall Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/ext2/balloc.c | 3 +-- fs/ext2/dir.c | 4 ++-- 2 files changed, 3 insertions(+), 4 deletions(-) diff --git a/fs/ext2/balloc.c b/fs/ext2/balloc.c index e7b2baf..c834f512 100644 --- a/fs/ext2/balloc.c +++ b/fs/ext2/balloc.c @@ -245,8 +245,7 @@ restart: prev = rsv; } printk("Window map complete.\n"); - if (bad) - BUG(); + BUG_ON(bad); } #define rsv_window_dump(root, verbose) \ __rsv_window_dump((root), (verbose), __FUNCTION__) diff --git a/fs/ext2/dir.c b/fs/ext2/dir.c index a0995eb..dd9dbb2 100644 --- a/fs/ext2/dir.c +++ b/fs/ext2/dir.c @@ -41,8 +41,8 @@ static inline __le16 ext2_rec_len_to_disk(unsigned len) { if (len == (1 << 16)) return cpu_to_le16(EXT2_MAX_REC_LEN); - else if (len > (1 << 16)) - BUG(); + else + BUG_ON(len > (1 << 16)); return cpu_to_le16(len); } -- cgit v1.1
