    "content": "This patchset adds a new command-line option \"--in-memory\",\nwhich takes old debug options \"--huge-unlink\" and\n\"--no-shconf\", and enhances them with additional\nfunctionality. This will allow DPDK to reserve hugepages\nanonymously instead of using hugetlbfs mountpoints. Coupled\nwith the fact that this option also effectively enables both\n\"--no-shconf\" and \"--huge-unlink\" modes, DPDK will be able\nto run entirely in memory and not create any shared files\nwhile running - neither hugepages nor any runtime data.\n\nThis will, of course, disable secondary processes, but for\nuse-cases this is targeted at (containers etc.), this is\nnot a problem.\n\nOlder revisions had kernel support at 4.14+ and also\nrequired a fairly new glibc, but now due to not using memfd\nand using mmap() instead, minimum supported kernel version\nhas dropped to 3.8.\n\nv2->v3 changes:\n- Fix compile issue in patch 9 (now 8)\n- Drop deprecation notice (will be sent separately)\n\nv1->v2 changes:\n- Rebase on latest master\n- Fix patch 5 to include check from patch 6 as commit message\n  states\n\nRFC->v1 changes:\n- Dropped memfd, using anonymous mmap() instead\n- Do not deprecate old command-line parameters, instead\n  use them as they are, and add a deprecation notice to\n  remove them in the next release.\n\nAnatoly Burakov (8):\n  fbarray: support no-shconf mode\n  ipc: add support for no-shconf mode\n  eal: add support for no-shconf for hugepage info\n  eal: add support for no-shconf in hugepage data file\n  eal: do not create runtime dir in no-shconf mode\n  mem: add support for hugepage-unlink mode\n  eal: add --in-memory option\n  mem: support in-memory mode\n\n lib/librte_eal/bsdapp/eal/eal.c               |   3 +-\n lib/librte_eal/bsdapp/eal/eal_hugepage_info.c |   4 +\n lib/librte_eal/common/eal_common_fbarray.c    |  71 +++++----\n lib/librte_eal/common/eal_common_options.c    |  20 ++-\n lib/librte_eal/common/eal_common_proc.c       |  25 +++\n lib/librte_eal/common/eal_internal_cfg.h      |   4 +\n lib/librte_eal/common/eal_options.h           |   2 +\n lib/librte_eal/linuxapp/eal/eal.c             |   3 +-\n .../linuxapp/eal/eal_hugepage_info.c          |  95 +++++++----\n lib/librte_eal/linuxapp/eal/eal_memalloc.c    | 150 ++++++++++++------\n lib/librte_eal/linuxapp/eal/eal_memory.c      |  16 +-\n 11 files changed, 276 insertions(+), 117 deletions(-)"
