A struct resource represents the address space consumed by a device. We should not modify that resource while the device is actively using the address space. For VFs, pci_iov_update_resource() enforces this by printing a warning and doing nothing if the VFE (VF Enable) and MSE (VF Memory Space Enable) bits are set. Previously, both sriov_enable() and sriov_disable() called the pcibios_sriov_disable() arch hook, which may update the struct resource, while VFE and MSE were enabled. This effectively dropped the resource update pcibios_sriov_disable() intended to do. Disable VF memory decoding before calling pcibios_sriov_disable().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
