From 97955f6941f0e7dea64dea22711382daf1db2f76 Mon Sep 17 00:00:00 2001 From: Deming Wang Date: Thu, 6 Oct 2022 23:03:45 -0400 Subject: mm/mincore.c: use vma_lookup() instead of find_vma() Using vma_lookup() verifies the start address is contained in the found vma. This results in easier to read the code.
