KMSAN bugs can only be tested on https://github.com/google/kmsan.git tree
because KMSAN tool is not upstreamed yet.

Another try:
#syz test: https://github.com/google/kmsan.git master
5.4-rc8 as in this kmsan.git tree should have
d9d4b1e46d9543a82c23f6df03f4ad697dab361b (was included in 5.4-rc6 when
the original syzbot issue was based on a 5.4-rc3)
Cheers,
Benjamin
