Yep, this has been fixed independently by https://lkml.kernel.org/r/20260107-export-vrealloc_node_align_noprof-v1-1-a581bec13054@google.com
It would be nice to reorder the patches so that the fix is applied before the kunit patch.

No probs, I reordered the application order:

: vmalloc-export-vrealloc_node_align_noprof.patch
: #
: mm-kasan-kunit-extend-vmalloc-oob-tests-to-cover-vrealloc.patch
: mm-kasan-kunit-extend-vmalloc-oob-tests-to-cover-vrealloc-fix.patch
