From: Julia Lawall <julia@xxxxxxx> romfs_iget returns an ERR_PTR value in an error case instead of NULL. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @match exists@ expression x, E; statement S1, S2; @@ x = romfs_iget(...) ... when != x = E ( * if (x == NULL || ...) S1 else S2 | * if (x == NULL && ...) S1 else S2 ) // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- fs/romfs/super.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/fs/romfs/super.c b/fs/romfs/super.c index 4ab3c03..7f733fb 100644 --- a/fs/romfs/super.c +++ b/fs/romfs/super.c @@ -528,7 +528,7 @@ static int romfs_fill_super(struct super_block *sb, void *data, int silent) pos = (ROMFH_SIZE + len + 1 + ROMFH_PAD) & ROMFH_MASK; root = romfs_iget(sb, pos); - if (!root) + if (IS_ERR(root)) goto error; sb->s_root = d_alloc_root(root); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
