[PATCH v2 repost 0/7] Extend virtio-balloon for fast (de)inflating & fast live migration
This patchset is for kernel and contains two parts of change to the
virtio-balloon.
One is the change for speeding up the inflating & deflating process,
the main idea of this optimization is to use bitmap to send the page
information to host instead of the PFNs, to reduce the overhead of
virtio data transmission, address translation and madvise(). This can
help to improve the performance by

[PATCH] virtio: Do not drop __GFP_HIGH in alloc_indirect
From: Michal Hocko <mhocko at suse.com>
b92b1b89a33c ("virtio: force vring descriptors to be allocated from
lowmem") tried to exclude highmem pages for descriptors so it cleared
__GFP_HIGHMEM from a given gfp mask. The patch also cleared __GFP_HIGH
which doesn't make much sense for this fix because __GFP_HIGH only
controls access to memory reserves and it doesn't have any

That was actually my original argument in the original thread - that
the only new interface people might want is one that just tells how
many of those MAX_ORDER-1 pages there are.
