SubjectRe: [PATCH 1/2] zram: fix crashes due to use of cpu hotplug multistate

Which part of it?

If there is a driver/subsystem code that can't handle the reverse
operation to modprobe, it clearly can't handle error handling during
modprobe (which, one would hope, is supported), and should be fixed.

If there is a particular issue in kernel dynamic linker that causes crash
on module removal, we'd better off fixing it. Is there one such that makes
you claim module removal unsupported?

Thanks,
