Subject: [PATCH 05/13] IB/umem: update to new mmu_notifier semantic
Date: Thu, 31 Aug 2017 17:17:30 -0400 [thread overview]
Message-ID: <20170831211738.17922-6-jglisse@redhat.com> (raw)
In-Reply-To: <20170831211738.17922-1-jglisse@redhat.com>
From: JA(C)rA'me Glisse <jglisse@redhat.com>
Call to mmu_notifier_invalidate_page() are replaced by call to
mmu_notifier_invalidate_range() and thus call are bracketed by
call to mmu_notifier_invalidate_range_start()/end()
Remove now useless invalidate_page callback.
