Agreed. I was more thinking about catching "... %p" and saying that we'd rather prefer either "... %p," or "... %p " or "... %p\n". Doesn't sound so complex, can probably catch something fishy one day (or may be not), and more or less is visible to checkpatch.

Right. One example might be XFS alert("%s: Bad regular inode %Lu, ptr "PTR_FMT, __func__, ip->i_ino, ip); where PTR_FMT is #ifdef DEBUG # define PTR_FMT "%px" #else # define PTR_FMT "%p" #endif -ss
