Sometimes, a kernel-patch series comes with an exciting, sexy title. Other
times, the mailing lists are full of patches with titles like “remote
per-cpu lists drain support“. For many, the patches associated with
that title will be just as dry as the title itself. But, for those who are
interested in such things — a group that includes many LWN readers —
this short patch series from Nicolas Saenz Julienne gives some
insight into just what is required to make the kernel’s page allocator as
fast — and as robust — as developers can make it.
