From 8d4b69002e56e93f1cfe8bb863846ecde3990032 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 29 Apr 2008 00:59:12 -0700 Subject: [PATCH] fs/affs/file.c: 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 Cc: Roman Zippel Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/affs/file.c | 21 +++++++-------------- 1 file changed, 7 insertions(+), 14 deletions(-) diff --git a/fs/affs/file.c b/fs/affs/file.c index 6e0c9399200e..e87ede608f77 100644 --- a/fs/affs/file.c +++ b/fs/affs/file.c @@ -325,8 +325,7 @@ affs_get_block(struct inode *inode, sector_t block, struct buffer_head *bh_resul pr_debug("AFFS: get_block(%u, %lu)\n", (u32)inode->i_ino, (unsigned long)block); - if (block > (sector_t)0x7fffffffUL) - BUG(); + BUG_ON(block > (sector_t)0x7fffffffUL); if (block >= AFFS_I(inode)->i_blkcnt) { if (block > AFFS_I(inode)->i_blkcnt || !create) @@ -493,8 +492,7 @@ affs_do_readpage_ofs(struct file *file, struct page *page, unsigned from, unsign u32 tmp; pr_debug("AFFS: read_page(%u, %ld, %d, %d)\n", (u32)inode->i_ino, page->index, from, to); - if (from > to || to > PAGE_CACHE_SIZE) - BUG(); + BUG_ON(from > to || to > PAGE_CACHE_SIZE); kmap(page); data = page_address(page); bsize = AFFS_SB(sb)->s_data_blksize; @@ -507,8 +505,7 @@ affs_do_readpage_ofs(struct file *file, struct page *page, unsigned from, unsign if (IS_ERR(bh)) return PTR_ERR(bh); tmp = min(bsize - boff, to - from); - if (from + tmp > to || tmp > bsize) - BUG(); + BUG_ON(from + tmp > to || tmp > bsize); memcpy(data + from, AFFS_DATA(bh) + boff, tmp); affs_brelse(bh); bidx++; @@ -540,8 +537,7 @@ affs_extent_file_ofs(struct inode *inode, u32 newsize) if (IS_ERR(bh)) return PTR_ERR(bh); tmp = min(bsize - boff, newsize - size); - if (boff + tmp > bsize || tmp > bsize) - BUG(); + BUG_ON(boff + tmp > bsize || tmp > bsize); memset(AFFS_DATA(bh) + boff, 0, tmp); AFFS_DATA_HEAD(bh)->size = cpu_to_be32(be32_to_cpu(AFFS_DATA_HEAD(bh)->size) + tmp); affs_fix_checksum(sb, bh); @@ -560,8 +556,7 @@ affs_extent_file_ofs(struct inode *inode, u32 newsize) if (IS_ERR(bh)) goto out; tmp = min(bsize, newsize - size); - if (tmp > bsize) - BUG(); + BUG_ON(tmp > bsize); AFFS_DATA_HEAD(bh)->ptype = cpu_to_be32(T_DATA); AFFS_DATA_HEAD(bh)->key = cpu_to_be32(inode->i_ino); AFFS_DATA_HEAD(bh)->sequence = cpu_to_be32(bidx); @@ -683,8 +678,7 @@ static int affs_write_end_ofs(struct file *file, struct address_space *mapping, if (IS_ERR(bh)) return PTR_ERR(bh); tmp = min(bsize - boff, to - from); - if (boff + tmp > bsize || tmp > bsize) - BUG(); + BUG_ON(boff + tmp > bsize || tmp > bsize); memcpy(AFFS_DATA(bh) + boff, data + from, tmp); AFFS_DATA_HEAD(bh)->size = cpu_to_be32(be32_to_cpu(AFFS_DATA_HEAD(bh)->size) + tmp); affs_fix_checksum(sb, bh); @@ -732,8 +726,7 @@ static int affs_write_end_ofs(struct file *file, struct address_space *mapping, if (IS_ERR(bh)) goto out; tmp = min(bsize, to - from); - if (tmp > bsize) - BUG(); + BUG_ON(tmp > bsize); memcpy(AFFS_DATA(bh), data + from, tmp); if (buffer_new(bh)) { AFFS_DATA_HEAD(bh)->ptype = cpu_to_be32(T_DATA); -- 2.30.2
