From 552657b7b3343851916fde7e4fd6bfb6516d2bcb Mon Sep 17 00:00:00 2001 From: chenqiwu Date: Mon, 6 Apr 2020 20:08:33 -0700 Subject: mm: fix ambiguous comments for better code readability The parameter of remap_pfn_range() @pfn passed from the caller is actually a page-frame number converted by corresponding physical address of kernel memory, the original comment is ambiguous that may mislead the users. Meanwhile, there is an ambiguous typo "VMM" in the comment of vm_area_struct. So fixing them will make the code more readable.
