Re: [PATCH v3 v3 1/2] selftests/harness: order TEST_F and XFAIL_ADD constructors

On Wed, 25 Feb 2026 19:14:50 +0800 Sun Jian wrote:

TEST_F() allocates and registers its struct __test_metadata via mmap()
inside its constructor, and only then assigns the
_##fixture_##test##_object pointer.

XFAIL_ADD() runs in a constructor too and reads
_##fixture_##test##_object to initialize xfail->test. If XFAIL_ADD runs
first, xfail->test can be NULL and the expected failure will be reported
as FAIL.

Use constructor priorities to ensure TEST_F registration runs before
XFAIL_ADD, without adding extra state or runtime lookups.

Hi Shuah!

Any preference which one of us takes this series?
No real preference here, just slight preference to ship it as 
a fix to 7.0 rather than via -next.
