Sorry, but I am reassigning back and bumping severity to stop
migration, as this is a kernel regression, as a stable userspace
interface was removed, which breaks booting existing systems. Hence I
am quite sure the new kernel should not move to testing for the time
being.
We might (or might not, still to be seen, given detecting mount options
that a kernel support is an absolute mess and it risks breaking booting
with the LTS kernels) put in a workaround in userspace in a while, but
this really should be reverted in the kernel. If mount options are no
longer required, they should simply remain as no-ops.
