From 767e5ee54ed75a1a89d92c872d82f3fe72c15650 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 1 Apr 2020 21:07:55 -0700 Subject: [PATCH] mm: add pagemap.h to the fine documentation The documentation currently does not include the deathless prose written to describe functions in pagemap.h because it's not included in any rst file. Fix up the mismatches between parameter names and the documentation and add the file to mm-api.
