Merge tag 'for-7.0/io_uring-zcrx-large-buffers-20260206' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux
Pull io_uring large rx buffer support from Jens Axboe:
"Now that the networking updates are upstream, here's the support for
large buffers for zcrx.
Using larger (bigger than 4K) rx buffers can increase the effiency of
zcrx. For example, it's been shown that using 32K buffers can decrease
CPU usage by ~30% compared to 4K buffers"
