528	Address space area leak in remote_ahci_read/write_blocks()	Jakub Jermář		"It looks like there is a leak of a shared address space area in `remote_ahci_write_blocks()` and `remote_ahci_read_blocks()`:

{{{
        void *buf;
        async_share_out_finalize(cid, &buf);

        const uint64_t blocknum =
            (((uint64_t) (DEV_IPC_GET_ARG1(*call))) << 32) |
            (((uint64_t) (DEV_IPC_GET_ARG2(*call))) & 0xffffffff);
        const size_t cnt = (size_t) DEV_IPC_GET_ARG3(*call);

        const int ret = ahci_iface->read_blocks(fun, blocknum, cnt, buf);

        async_answer_0(callid, ret);
}
}}}

`buf` is passed to `ahci_read/write_blocks()`, but it is never as_destroy()'ed in either of them nor in any other part of the ahci driver or `libdrv`."	defect	new	major		helenos/lib/other	mainline
