From d72d946d0b649b79709b99b9d5cb7269fff8afaa Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Mon, 21 Apr 2014 15:25:58 +0200 Subject: [PATCH] KVM: async_pf: kill the unnecessary use_mm/unuse_mm async_pf_execute() async_pf_execute() has no reasons to adopt apf->mm, gup(current, mm) should work just fine even if current has another or NULL ->mm. Recently kvm_async_page_present_sync() was added insedie the "use_mm" section, but it seems that it doesn't need current->mm too.
