Yes, it might be a bit improper to use -EBADFD here to indicate this
special scenario, or it can be
if (IS_ERR(tgt)) {
if (PTR_ERR(tgt) != -EBADFD) /* hmm, this might not needed, needs
further check */
return PTR_ERR(tgt);
if (lsm && !lmv_is_known_hash_type(lsm->lsm_md_hash_type)) {
ŠŠ..
} else {
return PTR_ERR(tgt);
}
}
