Revision aac2fea94f7a3df8ad1eeb477eb2643f81fd5393 authored by Kirill A. Shutemov on 10 August 2017, 22:24:27 UTC, committed by Linus Torvalds on 10 August 2017, 22:54:07 UTC
MMU notifiers can sleep, but in page_mkclean_one() we call
mmu_notifier_invalidate_page() under page table lock.
Let's instead use mmu_notifier_invalidate_range() outside
page_vma_mapped_walk() loop.
[jglisse@redhat.com: try_to_unmap_one() do not call mmu_notifier under ptl]
