Changes since v1 [1]: - split out the new warning into its own patch (Bjorn) - include the provisional fix to the pci_reset_bus() path [1]: http://lore.kernel.org/r/171709637423.1568751.11773767969980847536.stgit@xxxxxxxxxxxxxxxxxxxxxxxxx Hi Bjorn, Here is the targeted revert of the cfg_access_lock lockdep infrastructure, but with the new proposed warning for catching "unlocked pci_bridge_secondary_bus_reset()" events broken out into its own change. I also included the proposed fix for at least one known case where pci_bridge_secondary_bus_reset() is being called without cfg_access_lock. Given there may be more cases to unwind, and the fact that I am not convinced patch3 will be problem free I would, as you suggested, consider patch2 and patch3 v6.11 material. Patch1 is urgent for v6.10-rc to put out these lockdep false positive reports. --- Dan Williams (3): PCI: Revert the cfg_access_lock lockdep mechanism PCI: Warn on missing cfg_access_lock during secondary bus reset PCI: Add missing bridge lock to pci_bus_lock() drivers/pci/access.c | 4 ---- drivers/pci/pci.c | 8 +++++++- drivers/pci/probe.c | 3 --- include/linux/lockdep.h | 5 ----- include/linux/pci.h | 2 -- 5 files changed, 7 insertions(+), 15 deletions(-) base-commit: 56fb6f92854f29dcb6c3dc3ba92eeda1b615e88c
