[PATCH v2 00/13] PCI: let the core manage slot names

[Alex Chiang <achiang@hp.com>]

Hi Jesse,

This is v2 of the series that implements a series of changes
that allows the PCI core to manage slot names, rather than
individual hotplug drivers.

It addresses comments raised during the first round of review,
most notably the bug that Kenji-san found of possible false name
collisions.

This series applies against linux-next.

I'm including the previous explanation/justification to remind
folks of the raison d'etre for this patchset.

Thanks.

There are several benefits to this approach:

        1) The core can prevent duplicate slot names on systems
           with broken firmware.

        2) Since the kobject core keeps a copy of the slot name,
           there is no need for each driver to manage a separate
           copy, especially since the core can rename slots from
           underneath drivers. We save runtime memory by only
           referencing the kobject name.

        2.a) The PCI hotplug core doesn't need its own reference
             for slot name either.

        3) Individual hotplug drivers become just a little bit
           simpler by pushing as many kzalloc() calls for 'name'
           down into the PCI core as possible.
