2. Place the cursor on "page_map_count(page)" function invocation (mm/
page_alloc.c:433) and invoke etags-select-find-tag-at-point.
It will display among others the "reset_page_mapcount" as a candidate
to jump. I think that it is not a good candidate.
For me it looks rather like TAGS problem since C-u M-. leads You to
that symbol as well.
Although you say in a later message that this is OK, I'm not sure it is.
I think it might be confusing two function names with the same suffix.
It should be an easy enough fix ... I need to create a test case and sort
things out.
