From 37bc2ff506b184411e4cc80f111c638b2b4c83d4 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Fri, 12 Apr 2024 20:35:00 +0100 Subject: mm: return the address from page_mapped_in_vma() The only user of this function calls page_address_in_vma() immediately after page_mapped_in_vma() calculates it and uses it to return true/false. Return the address instead, allowing memory-failure to skip the call to page_address_in_vma().
