[RFC PATCH v2.2 01/28] mm/damon/core: introduce struct damon_probe

[SeongJae Park <sj@kernel.org>]

Introduce a data structure for data attribute probe.  It is just a
linked list header at this step.  It will be extended in a way that it
can determine if a given memory has a specific data attribute.
