Subject[PATCH v4 00/12] PCI core learns hotplug
Date
We're getting close to the new merge window, and I _think_ this
patch series is ready for consideration. Notably:

- multiple rescans/removes of devices with and without bridges
- verified that resource allocation after multiple remove/rescan
cycles is the same as what we had during initial boot
- fixes the complete suckage of fakephp (that I created)
- doesn't affect existing hotplug drivers
- tested on x86 and ia64 platforms

Please review, and consider testing. For testing ease, you can pull
from my git branch:

git://git.kernel.org/pub/scm/linux/kernel/git/achiang/pci-hotplug.git
branch 'test-20090318' is what you want

Note, this test branch does contain the small assorted patches in AER
and the PCIe portdriver that I fixed along the way, but does not contain
the sysfs callback mutex that I introduced to protect myself from
Vegard Nossum. ;) If you want to hammer away at the sysfs interface,
please apply this patch on top:

http://thread.gmane.org/gmane.linux.kernel/806648

What I'm continuing to do:

- investigate converting existing hotplug drivers to use
new pci_rescan_bus() interface

Thanks.

/ac

v3 -> v4:
- protect sysfs interfaces with mutex
- undo changes in pci_do_scan_bus
- introduce pci_rescan_bus instead
- do not initialize bridges more than once

v2 -> v3:
- properly remove device with internal bridge
- added Kenji Kaneshige's pci_is_root_bus() interface
- dropped whitespace cleanups for another time

v1 -> v2:
- incorporated lots of Trent Piepho's work
- beefed up pci_do_scan_bus as heavy lifter for rescanning
- small bugfixes folded into earlier patches to get everything working

Alex Chiang (8):
PCI Hotplug: schedule fakephp for feature removal
PCI Hotplug: rename legacy_fakephp to fakephp
PCI: Introduce /sys/bus/pci/devices/.../rescan
PCI: Introduce /sys/bus/pci/devices/.../remove
PCI: Introduce /sys/bus/pci/rescan
PCI: Introduce pci_rescan_bus()
PCI: do not initialize bridges more than once
PCI: always scan child buses

Kenji Kaneshige (1):
PCI: pci_is_root_bus helper

Trent Piepho (3):
PCI Hotplug: restore fakephp interface with complete reimplementation
PCI: pci_scan_slot() returns newly found devices
PCI: don't scan existing devices
