From bac3cf4d01d43b587c873360dc8c84e3b570b344 Mon Sep 17 00:00:00 2001 From: John Hubbard Date: Tue, 13 Oct 2020 16:51:14 -0700 Subject: mm, dump_page: rename head_mapcount() --> head_compound_mapcount() Rename head_pincount() --> head_compound_pincount(). These names are more accurate (or less misleading) than the original ones. Signed-off-by: John Hubbard Signed-off-by: Andrew Morton Cc: Qian Cai Cc: Matthew Wilcox Cc: Vlastimil Babka Cc: Kirill A.
