We were assuming that it was OK to do a GFP_KERNEL allocation in page fault context. That appears to be largely true, but filesystems are permitted to override that in their setting of mapping->gfp_flags, which the VM then massages into vmf->gfp_flags. No practical difference for now, but there may come a day when we would have surprised a filesystem.
