Description

seems to be leaking allocated page if there was crypto init error:

 

        __page = alloc_page(GFP_KERNEL);
        if (__page == NULL)
                return -ENOMEM;
        req = cfs_crypto_hash_init(cfs_alg, NULL, 0);
        if (IS_ERR(req)) {
                CERROR("%s: unable to initialize checksum hash %s\n",
                       tgt_name(tgt), cfs_crypto_hash_name(cfs_alg));
                return PTR_ERR(req);
        }
