Hi all,

After merging the tip tree, today's linux-next started crashing running
arm64 KUnit like this:

[18:12:16] [PASSED] split unwrit extent to 3 extents and convert 2nd half writ (non-endio, zeroout) (highlevel)
[18:12:16] =============== [PASSED] test_split_convert ================
[18:12:16] ================ [PASSED] ext4_extents_test ================
[18:12:16] ============== ext4_mballoc_test (7 subtests) ==============
Command '['qemu-system-aarch64', '-nodefaults', '-m', '1024', '-kernel', '/tmp/next/arm64_kunit/arch/arm64/boot/Image.gz', '-append', 'kunit.enable=1 console=ttyAMA0 kunit_shutdown=reboot', '-no-reboot', '-nographic', '-accel', 'kvm', '-accel', 'hvf', '-accel', 'tcg', '-serial', 'stdio', '-machine', 'virt', '-cpu', 'max']' timed out after 300 seconds

I didn't figure out what the source of the issue was, I merged the tip
tree from 20260309 instead.
