A simplified version of the semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression ret; expression e; position p; @@ -ret = 0; ... when != ret = e return - ret + 0 ; // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- fs/ufs/truncate.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/fs/ufs/truncate.c b/fs/ufs/truncate.c index f04f89f..a17f0a9 100644 --- a/fs/ufs/truncate.c +++ b/fs/ufs/truncate.c @@ -72,7 +72,6 @@ static int ufs_trunc_direct(struct inode *inode) u64 frag1, frag2, frag3, frag4, block1, block2; unsigned frag_to_free, free_count; unsigned i, tmp; - int retry; UFSD("ENTER: ino %lu\n", inode->i_ino); @@ -81,7 +80,6 @@ static int ufs_trunc_direct(struct inode *inode) frag_to_free = 0; free_count = 0; - retry = 0; frag1 = DIRECT_FRAGMENT; frag4 = min_t(u64, UFS_NDIR_FRAGMENT, ufsi->i_lastfrag); @@ -164,7 +162,7 @@ next1: next3: UFSD("EXIT: ino %lu\n", inode->i_ino); - return retry; + return 0; } @@ -176,7 +174,6 @@ static int ufs_trunc_indirect(struct inode *inode, u64 offset, void *p) void *ind; u64 tmp, indirect_block, i, frag_to_free; unsigned free_count; - int retry; UFSD("ENTER: ino %lu, offset %llu, p: %p\n", inode->i_ino, (unsigned long long)offset, p); @@ -188,7 +185,6 @@ static int ufs_trunc_indirect(struct inode *inode, u64 offset, void *p) frag_to_free = 0; free_count = 0; - retry = 0; tmp = ufs_data_ptr_to_cpu(sb, p); if (!tmp) @@ -248,7 +244,7 @@ static int ufs_trunc_indirect(struct inode *inode, u64 offset, void *p) UFSD("EXIT: ino %lu\n", inode->i_ino); - return retry; + return 0; } static int ufs_trunc_dindirect(struct inode *inode, u64 offset, void *p) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
