Alex Williamson ac91c87295 PCI: Fix "try" semantics of bus and slot reset ... [ Upstream commit ddefc033ee ] The commit referenced below introduced device locking around save and restore of state for each device during a PCI bus "try" reset, making it decidely non-"try" and prone to deadlock in the event that a device is already locked. Restore __pci_reset_bus() and __pci_reset_slot() to their advertised locking semantics by pushing the save and restore functions into the branch where the entire tree is already locked. Extend the helper function names with "_locked" and update the comment to reflect this calling requirement. Fixes: b014e96d1a ("PCI: Protect pci_error_handlers->reset_notify() usage with device_lock()") Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Sinan Kaya <okaya@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-01-27 14:50:30 +01:00
