fs/proc/task_mmu: convert pagemap_hugetlb_range() to work on folios
Patch series "fs/proc/task_mmu: convert hugetlb functions to work on folis".
Let's convert two more functions, getting rid of two more page_mapcount()
calls.
This patch (of 2):
Let's get rid of another page_mapcount() check and simply use
folio_likely_mapped_shared(), which is precise for hugetlb folios.
While at it, also check for PMD table sharing, like we do in
smaps_hugetlb_range().
No functional change intended, except that we would now detect hugetlb
folios shared via PMD table sharing correctly.
