Hi, I think that the subject and patch description need to be reworked. We can see easily enough from the code what is being done.

Please do run checkpatch.pl --strict --codespell and, within reason, correct the issues it flags. Please make sure that allmodconfig builds compile.

Also, while it mat address a compiler warning, it's not claear to me how this is related to the const change that is the subject of this patch. > kfree(buf); > if (ret) > return ret; ... > @@ -311,9 +312,9 @@ static int ceph_key_preparse(struct key_preparsed_payload *prep) > if (!ckey) > goto err; > > - /* TODO ceph_crypto_key_decode should really take const input */ > - p = (void *)prep->data; > - ret = ceph_crypto_key_decode(ckey, &p, (char*)prep->data+datalen); > + p = prep->data; > + ret = ceph_crypto_key_decode(ckey, &p, \ > + (const void *)((const char *)prep->data + datalen)); I don't think you need the cast to void * here either. > if (ret < 0) > goto err_ckey; > ...
