A good deal of the structures we map into here aren't accessed very often at all, and Fedora 26 has exposed an issue where after creating a heap of channels, BAR2 space would run out, and we'd need to make use of the slow path while accessing important structures like page tables. This implements an LRU on BAR2 space, which allows eviction of mappings that aren't currently needed, to make space for other objects. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
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.
