Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git
tags/fuse-update-6.14
Add support for io-uring communication between kernel and userspace
using IORING_OP_URING_CMD (Bernd Schubert). Following features enable
gains in performance compared to the regular interface:
- Allow processing multiple requests with less syscall overhead
- Combine commit of old and fetch of new fuse request
- CPU/NUMA affinity of queues
Patches were reviewed by several people, including Pavel Begunkov,
io-uring co-maintainer.
Thanks,
Miklos
