Hi,
based on regular regression check on linux-next tree as KVM/QEMU based guest VM
kernel, there are following error observed since next-20240709.
it's 100% reproduced on my local setup.
based on bisect, it points to linux-next merge commit:
first bad commit: [28ab424895157dfea418c12418c5d0fc9263e850] Merge branch
'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git
while no further check for vhost.git repo possible on my side,
can somebody help to take a look?
