Sorry, I got confused and missed the meeting. I notice notes are at

https://ircbot.wl.linuxfoundation.org/meetings/cip/2023/01/cip.2023-01-05-13.02.log.html

so I'll go through them.

I did lot of reviews on 5.10.162 and 163. There is long series with

commit 466f98dac2f4908c8722b5fb23d0a1e481672f2c
Author: Jens Axboe <axboe@kernel.dk>
Date: Thu Dec 22 14:30:11 2022 -0700

io_uring: import 5.15-stable io_uring

No upstream commit exists.

This imports the io_uring codebase from 5.15.85, wholesale. Changes
from that code base:

- Drop IOCB_ALLOC_CACHE, we don't have that in 5.10.
- Drop MKDIRAT/SYMLINKAT/LINKAT. Would require further VFS backports,
and we don't support these in 5.10 to begin with.
- sock_from_file() old style calling convention.
- Use compat_get_bitmap() only for CONFIG_COMPAT=y

...which is 16000 lines of changes. There's no reasonable way to
review that. (And it probably has implications for 4.4 / 4.19).

I guess best way forward is to still take the patches even through we
can't review them, but if anyone is using io_uring (which I'd _not_
recommend at this moment), we might want to do some extra testing, or
get the users to test it.

Best regards,
Pavel
