Subject: [RFC PATCH 0/5] PCI: introduce hotplug safe bus searching interfaces
Date: Mon, 12 Mar 2012 01:48:24 +0800	[thread overview]
Message-ID: <1331488109-13466-1-git-send-email-jiang.liu@huawei.com> (raw)

This patchset is based on Yinghai's pci root bus hotplug v2, please refer to:
http://www.spinics.net/lists/linux-pci/msg14194.html.
The first three patches are minor bug fixes against the pci root bus hotplug
code. The forth/fifth is a proposal to introduce a series of pci hotplug safe
interfaces to search pci buses. This is aimed to solve possible race
conditions when doing pci root bus/pci bus hotplug. The proposal is here to
show the idea, and hasn't been fully tested yet. If it's on the right way,
I will refine it and do thorough tests.

Jiang Liu (5):
  Fix device reference count leakage in pci_dev_present()
  Correctly clean up pci root buses in function pci_remove_bus()
  Fix an access-after-free issue in function pci_stop_and_remove_bus()
  Introduce hotplug-safe pci bus searching interfaces
  Replace old pci bus searching function calls with hotplug safe ones
