FYI, we noticed the following commit:
commit: df33767d9fe0ca93c606cc9042df05e5045c8158 ("uuid: hoist helpers uuid_equal() and uuid_copy() from xfs") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: boot
on test machine: qemu-system-x86_64 -enable-kvm -m 420M
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
