Jens Axboe describesthe new io_uring features that will be a part of the 6.10 kernelrelease.

Bundles are multiple buffers used in a single operation. On thereceive side, this means a single receive may utilize multiplebuffers, reducing the roundtrip through the networking stack from Nper N buffers to just a single one. On the send side, this alsoenables better handling of how an application deals with sends froma socket, eliminating the need to serialize sends on a singlesocket. Bundles work with provided buffers, hence this feature alsoadds support for provided buffers for send operations.
