REGRESSION 5.19-rc1: virtio: harden vring IRQ

["Theodore Ts'o" <tytso@mit.edu>]

[-- Attachment #1: Type: text/plain, Size: 830 bytes --]

I can no longer boot v5.19-rc1 on a Google Compute Engine VM.  This
bisected to commit 8b4ec69d7e09 ("virtio: harden vring IRQ").  Its
parent commit, be83f04d2529 ("virtio: allow to unbreak virtqueue")
does successfully boot, so it appears to be caused by commit
8b4ec69d7e09.

I've attached the console log and the config file which I used (which
was generated by using "kvm-xfstests install-kconfig"[1] which is
essentially a "make olddefconfig" of [2]

[1] https://github.com/tytso/xfstests-bld/blob/master/kernel-build/install-kconfig
[2] https://github.com/tytso/xfstests-bld/blob/master/kernel-build/kernel-configs/x86_64-config-5.15

Unfortunately, commit 8b4ec69d7e09 doesn't revert cleanly against
v5.19-rc1, but I can look into figure out how to do revert it if
necessary.

Is this a known issue?

Thanks,

						- Ted
