[$] Redesigned workqueues for io_uring The
io_uring mechanism is a relatively new
interface for asynchronous I/O; it first appeared in the 5.1 kernel in
May. Since then, though, it has quickly grown in capabilities and in
users; now it appears that it is outgrowing some of the kernel
infrastructure that supports it. Thus, we have a proposal from Jens Axboe
(the io_uring maintainer) for
a new
workqueue subsystem for io_uring that hints at some interesting plans
for the future.
