Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Raghavendra K T Subject: lib/test_vmalloc.c: introduce xfail for failing tests Date: Wed, 2 Jul 2025 06:43:19 +0000 The test align_shift_alloc_test is expected to fail. Reporting the test as fail confuses to be a genuine failure. Introduce widely used xfail sematics to address the issue. Note: a warn_alloc dump similar to below is still expected: Call Trace: dump_stack_lvl+0x64/0x80 warn_alloc+0x137/0x1b0 ? __get_vm_area_node+0x134/0x140 Snippet of dmesg after change: Summary: random_size_align_alloc_test passed: 1 failed: 0 xfailed: 0 ..
