Well, it's enabled only for virtual pcie ports because I could hardly
enable it by default otherwise.

There is another delay in remove_board(), mst suggests removing that
too, and that surely would be something we can't do on physical
hardware ...

So I'd prefer to keep the name.

It's a module parameter so will show up in
/sys/module/pciehp/parameters/ and it is writable by root.

[ will address the other things mentioned in v2 ].

take care,
