From 8651a137e62ebfde3df95cbb1ca055d013ec5b9e Mon Sep 17 00:00:00 2001 From: Lorenzo Stoakes Date: Sat, 7 Jan 2023 00:00:05 +0000 Subject: mm: update mmap_sem comments to refer to mmap_lock The rename from mm->mmap_sem to mm->mmap_lock was performed in commit da1c55f1b272 ("mmap locking API: rename mmap_sem to mmap_lock") and commit c1e8d7c6a7a6 ("map locking API: convert mmap_sem comments"), however some incorrect comments remain. This patch simply corrects those comments which are obviously incorrect within mm itself.
