Patch series "Leave IRQs enabled for per-cpu page allocations", v3. This patch (of 2): free_unref_page_list() has neglected to remove pages properly from the list of pages to free since forever. It works by coincidence because list_add happened to do the right thing adding the pages to just the PCP lists. However, a later patch added pages to either the PCP list or the zone list but only properly deleted the page from the list in one path leading to list corruption and a subsequent failure. As a preparation patch, always delete the pages from one list properly before adding to another. On its own, this fixes nothing although it adds a fractional amount of overhead but is critical to the next patch.

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.
