Its filename was selftests-mm-allocate-6-hugepages-in-va_high_addr_switchsh.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Chunyu Hu Subject: selftests/mm: allocate 6 hugepages in va_high_addr_switch.sh Date: Sun, 21 Dec 2025 12:00:22 +0800 The va_high_addr_switch test requires 6 hugepages, not 5. If running the test directly by: ./va_high_addr_switch.sh, the test will hit a mmap 'FAIL' caused by not enough hugepages: mmap(addr_switch_hint - hugepagesize, 2*hugepagesize, MAP_HUGETLB): 0x7f330f800000 - OK mmap(addr_switch_hint , 2*hugepagesize, MAP_FIXED | MAP_HUGETLB): 0xffffffffffffffff - FAILED The failure can't be hit if run the tests by running 'run_vmtests.sh -t hugevm' because the nr_hugepages is set to 128 at the beginning of run_vmtests.sh and va_high_addr_switch.sh skip the setup of nr_hugepages because already enough.
