Call pci_assign_unassigned_root_bus_resources() instead of the simpler: pci_bus_size_bridges(bus); pci_bus_assign_resources(bus); pci_assign_unassigned_root_bus_resources() calls: __pci_bus_size_bridges(bus, add_list); __pci_bus_assign_resources(bus, add_list, &fail_head); so this should be equivalent as long as we're able to assign everything. If we were unable to assign something, previously we did nothing and left it unassigned, but after this patch, we will attempt to do some reallocation. Once we start honoring FW resource allocations, this will bring up the "reallocation" feature which can help making room for SR-IOV when necessary.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
