[PATCH io_uring-next/net-next v2 4/4] io_uring/notif: implement notification stacking

The network stack allows only one ubuf_info per skb, and unlike MSG_ZEROCOPY, each io_uring zerocopy send will carry a separate ubuf_info. That means that send requests can't reuse a previosly allocated skb and need to get one more or more of new ones. That's fine for large sends, but otherwise it

[PATCH io_uring-next/net-next v2 3/4] io_uring/notif: simplify io_notif_flush()

io_notif_flush() is partially duplicating io_tx_ubuf_complete(), so instead of duplicating it, make the flush call io_tx_ubuf_complete. Reviewed-by: Jens Axboe Signed-off-by: Pavel Begunkov --- io_uring/notif.c | 6 +++--- io_uring/notif.h | 9 +++-- 2 files changed, 6 insertions(+), 9 dele

[PATCH io_uring-next/net-next v2 2/4] net: add callback for setting a ubuf_info to skb

At the moment an skb can only have one ubuf_info associated with it, which might be a performance problem for zerocopy sends in cases like TCP via io_uring. Add a callback for assigning ubuf_info to skb, this way we will implement smarter assignment later like linking ubuf_info together. Note, it'

[PATCH io_uring-next/net-next v2 1/4] net: extend ubuf_info callback to ops structure

We'll need to associate additional callbacks with ubuf_info, introduce a structure holding ubuf_info callbacks. Apart from a more smarter io_uring notification management introduced in next patches, it can be used to generalise msg_zerocopy_put_abort() and also store ->sg_from_iter, which is curren

[PATCH io_uring-next/net-next v2 0/4] implement io_uring notification (ubuf_info) stacking

Please, don't take directly, conflicts with io_uring. To have per request buffer notifications each zerocopy io_uring send request allocates a new ubuf_info. However, as an skb can carry only one uarg, it may force the stack to create many small skbs hurting performance in many ways. The patchset
