Hi, do I understand it correctly that it's currently impossible to do TRIM with io_uring?

I've seen ioctl operation support patches but they were really recent. Will they allow TRIM? When can we expect to see them merged in the kernel?

// io_uring is really cool by the way, thanks for the work :)

Right, there's currently no way to do that. But we could make it happen, though.
