    "content": "It is already possible to use both DPDK in general and\nvirtio specifically, without hugetlbfs mounts, but\ncurrently virtio cannot be used without hugepage memory\n(i.e. with a --no-huge EAL switch) due to the fact that\nit needs to share memory with the backend.\n\nThis patchset uses memfd to create actual files backing\nanonymous memory. This enabled virtio to work not only\nwithout hugetlbfs, but without hugepages altogether,\nwhich could be useful in Cloud Native scenarios.\n\nAnatoly Burakov (2):\n  memalloc: allow setting up segment list fd's\n  mem: use memfd for no-huge mode\n\n lib/librte_eal/bsdapp/eal/eal_memalloc.c   |  6 +++\n lib/librte_eal/common/eal_memalloc.h       |  4 ++\n lib/librte_eal/linuxapp/eal/eal_memalloc.c | 16 ++++++++\n lib/librte_eal/linuxapp/eal/eal_memory.c   | 46 +++++++++++++++++++++-\n 4 files changed, 70 insertions(+), 2 deletions(-)"
