I like taking these checks into posix_acl_valid, but I think the patch submission needs a bit more work. All the patches are extremly whitespace mangled. And I don't think splitting them up makes a whole lot of sense, when we do API changes like this we usually fix up all callers. So please try to fix your mailer, merged them all into one, and maybe also chose a more descriptive subject line, e.g. Subject: take checks for NULL and error pointers into posix_acl_valid() And btw, at least the XFS change seems incorrect - previously we returned NULL acl pointer and this patch changes it to -EINVAL. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
