Hi Al,
After merging the vfs tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
arch/powerpc/kvm/../../../virt/kvm/kvm_main.c: In function 'hva_to_pfn_slow':
arch/powerpc/kvm/../../../virt/kvm/kvm_main.c:1379:35: error: 'start' undeclared (first use in this function)
npages = get_user_pages_unlocked(start, 1, &page, flags);
^
Caused by commit
eeb7c213c804 ("kvm: switch get_user_page_nowait() to get_user_pages_unlocked()")
I have applied the following fix patch for today:
