  "message": "DONOTMERGE: KVM: selftests: Fix MADV_COLLAPSE build failure on older toolchains\n\nAn equivalent commit has been submitted and accepted into a fixes\nbranch upstream, but hasn\u0027t made it yet. Keep this until that happens,\notherwise the selftests won\u0027t build.\n\nguest_memfd_test.c uses MADV_COLLAPSE unconditionally, but the\nconstant was only exposed in glibc 2.37. Distros still on older glibc\n(e.g. Debian Bookworm, glibc 2.36) cannot build the test.\n\nAdd a compile-time fallback that defines MADV_COLLAPSE to its\nkernel-ABI value when the libc header does not, matching the\nestablished selftest pattern for sometimes-missing libc constants\n(see selftests/bpf/uprobe_multi.c, selftests/mm/hugetlb-soft-offline.c).\n\nFixes: 9830209b4ae8 (\"KVM: selftests: Test MADV_COLLAPSE on guest_memfd\")\nSigned-off-by: Fuad Tabba \u003cfuad.tabba@linux.dev\u003e\n",
