From b47beff129c6193df3dd406f2db2628fcc09d1eb Mon Sep 17 00:00:00 2001 From: Chunyu Hu Date: Sun, 21 Dec 2025 12:00:21 +0800 Subject: selftests/mm: fix va_high_addr_switch.sh return value Patch series "Fix va_high_addr_switch.sh test failure - again", v2. The series address several issues exist for the va_high_addr_switch test: 1) the test return value is ignored in va_high_addr_switch.sh. 2) the va_high_addr_switch test requires 6 hugepages not 5. 3) the reurn value of the first test in va_high_addr_switch.c can be overridden by the second test. 4) the nr_hugepages setup in run_vmtests.sh for arm64 can be done in va_high_addr_switch.sh too. 5) update a comment for check_test_requirements. This patch: (of 5) The return value should be return value of va_high_addr_switch, otherwise a test failure would be silently ignored.
