The sole non-static function in err.c, pcie_do_recovery(), is only called from: * aer.c (if CONFIG_PCIEAER=y) * dpc.c (if CONFIG_PCIE_DPC=y, which depends on CONFIG_PCIEAER) * edr.c (if CONFIG_PCIE_EDR=y, which depends on CONFIG_PCIE_DPC) Thus, err.c need not be compiled if CONFIG_PCIEAER=n. Also, pci_uevent_ers() and pcie_clear_device_status(), which are called from err.c, can be #ifdef'ed away unless CONFIG_PCIEAER=y. Since x86_64_defconfig doesn't enable CONFIG_PCIEAER, this change may slightly reduce compile time for anyone doing a test build with that config.

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.
