Over time, some users experience slow downs in certain flash storage

So, if this is desirable, why doesn't the kernel do this on its own?
Why do we need a userspace component that just gets an event from the
kernel and then tells the kernel to do something? If this is generally
desirable, why is something as trivial as that not a kernel
functionality anyway?
