Commit 8c7424cff6 "nfsd4: don't try to encode conflicting owner if low on space" forgot to free conf->data in nfsd4_encode_lockt and before sign conf->data to NULL in nfsd4_encode_lock_denied, causing a leak. Worse, kfree() can be called on an uninitialized pointer in the case of a succesful lock (or one that fails for a reason other than a conflict). (Note that lock->lk_denied.ld_owner.data appears it should be zero here, until you notice that it's one arm of a union the other arm of which is written to in the succesful case by the memcpy(&lock->lk_resp_stateid, &lock_stp->st_stid.sc_stateid, sizeof(stateid_t)); in nfsd4_lock(). In the 32-bit case this overwrites ld_owner.data.)
