Hello everyone,
lately I have been looking into the io_uring functionality in the
kernel and apps that I use -- what could be a non-generic USE flag
shared by mpd and qemu?
I have noticed that currently 9 packages[1] have an io-uring USE
flag. All of them use it for enabling the use of io_uring
system calls.
The feature was introduced in 5.1 and the oldest we ship is 5.10
so I think there will be no compatibility issues.
Introducing a new io-uring global USE flag would encourage users
to enable it globally and simplify the configuration.
The USE description that I propose is
"Enable the use of io_uring system calls for efficient async IO".
Of course if there is something more fitting it should be chosen,
I have no hard opinions here.
What do you think about it?
Kind regards
Filip Kobierski

https://packages.gentoo.org/useflags/uring
So that's 12 packages.
And sys-apps/syd already uses io-uring unconditionally looks like.
I'm in support of this being a global.
Kind regards,
Jaco

I also think io-uring is a good candidate for a global use flag. Given
that there where no objections, please feel encouraged to propose a
tree-wide patch.
