[PATCH 0/2] LVM Cachevol and Integrity volumes break entire LVM VG

[Patrick Plenefisch]

In an effort to solve
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1061168 for myself,
I implemented basic support for cachevol and integrity volumes in LVM.

This is just an extension of the cachepool support that already
existed, and just like that support, I ignore all of the metadata and
just go for the data. This obviously means that writing to "writeback"
cachepools, and any raidintegrity volumes will cause corruption as
before, but as grub only reads files, I think that should be fine.

Without these patches, a system with /boot on a LV with cachevol or
integrity volumes will fail to boot

These patches are also available attached and at
