Well, I reviewed it but my though was that it should be built on the emerging
hotplug infrastructure.

I'm currently trying to move things like this into the user layer, so from a
design principle I don't want to have 90% using the user space stuff and 10%
using its in-kernel equivalent because that means we have two mechanisms to
maintain, thus doubling the work.

The problem you had with this was the 10ms requirement from removal
notification to removal completion. Several people have already suggested
that if that really is a hard and fast requirement, then you could simply
treat the removal as a surprise removal rather than a planned one and work on
fixing our surprise removal problems instead.

The bottom line is that I'm not convinced this can't be done using the
existing infrastructure or a generic enhancement to it.
