Kernel code can, at times, be quite inward looking; it often refers to
itself. To enable this introspection, the kernel has evolved several
mechanisms for identifying specific locations in the code and carrying out
actions related to those locations. The code-tagging
framework patch set, posted by Suren Baghdasaryan and Kent Overstreet,
is an attempt to replace various ad hoc implementations with a
single framework, and to add some new applications as well.

Memory management generally works at the level of pages, which typically
contain 4,096 bytes but may be larger. The kernel, though, has extended
the concept of pages to include compound pages, which are groups of
contiguous single pages. That, in turn, has made the definition of
what a "page" is a bit fuzzy. Matthew Wilcox has been working since last
year on a concept called "page folios" which is meant to bring the picture
back into focus; whether the memory-management community will accept it
remains unclear, though.
