    net: remove sock_iocb · 7cc05662
    Christoph Hellwig 提交于
    The sock_iocb structure is allocate on stack for each read/write-like
    operation on sockets, and contains various fields of which only the
    embedded msghdr and sometimes a pointer to the scm_cookie is ever used.
    Get rid of the sock_iocb and put a msghdr directly on the stack and pass
    the scm_cookie explicitly to netlink_mmap_sendmsg.
