What the heck is a "background colour"? :)
Good point, this is some jargon that we started using for MTE, the idea being that
the kernel could set a tag value (specified during mmap()) as "background colour" for
anonymous pages allocated in that range.
Anyway, this patch series is not about MTE. Andrey, for v20 (if any), I think it's
best to drop this last sentence to avoid any confusion.
