lsr: ls with io_uring

I remember getting in to a situation during the ext2 and spinning rust days where production directories had 500k files. ls processes were slow enough to overload everything. ls -F saved me there.

And filesystems got a lot better at lots of files. What filesystem was used here?

It's interesting how well busybox fares, it's written for size not speed iirc?

Two points are not enough to say it's sublinear. It might very well be some constant factor that becomes less and less important the bigger the linear factor becomes.

Or in other words 10000n+C < 10000(n+C)
