Patch series "mm/damon/core: hide core-private struct fields".

DAMON core structs hide core-private fields using 'private:' comment tags. It is incomplete and inconsistent. The linked list heads in a few structs, for example, are intended to be hidden, and always be used using the wrapper macros like damon_for_each_region(). But those were mistakenly marked as non-private. A few core layer-only fields were also mistakenly added as non-private.

This only encourages callers to directly use the private fields. It is easy to make mistakes, and difficult to control. Mark all such DAMON core struct fields as private.

Patches 1-8 mark the private fields for damon_region, damon_target, damos_quota_goal, damos_quota, damos_filter, damos, damon_filter and damon_probe, respectively. Patch 9 removes DAMON_SYSFS's direct access to core-private field, damon_ctx->ops. Finally patch 10 mark the private fields for damon_ctx.

This patch (of 10):

damon_region->list is intended to be used by only the DAMON core layer. But it is mistakenly not marked as private. Hide it from the callers by marking it private.
