From 7d4a8be0c4b2b7ffb367929d2b352651f083806b Mon Sep 17 00:00:00 2001 From: Alistair Popple Date: Tue, 10 Jan 2023 13:57:22 +1100 Subject: mm/mmu_notifier: remove unused mmu_notifier_range_update_to_read_only export mmu_notifier_range_update_to_read_only() was originally introduced in commit c6d23413f81b ("mm/mmu_notifier: mmu_notifier_range_update_to_read_only() helper") as an optimisation for device drivers that know a range has only been mapped read-only. However there are no users of this feature so remove it. As it is the only user of the struct mmu_notifier_range.vma field remove that also.
