[Qemu-devel] [PATCH] mm: hugetlb: initialize PG_reserved for tail pages of gigantig compound pages

11feeb498086a3a5907b8148bdf1786a9b18fc55 introduced a memory leak when KVM is run on gigantic compound pages. 11feeb498086a3a5907b8148bdf1786a9b18fc55 depends on the assumption that PG_reserved is identical for all head and tail pages of a compound page. So that if get_user_pages returns a tail pa

Now that the memory API is thread-safe, we can use it in virtio-blk-dataplane and replace hostmem.[ch]. This series does this, and also changes the vring API to use VirtQueueElement (with an eye towards migration). With this change, virtio-blk-dataplane is also safe against memory hot-unplug. Th
