The description of the memory.numa_stat file has been updated to clarify
that the output values can be in bytes or pages. This change ensures that
users are aware that the unit of measurement for memory values can vary
and should be verified by consulting the memory.stat

It's known that
workingset_*, pgdemote_* and pgpromote_success are counted in pages

You mean "bytes or pages". Right?
