[PATCH 0/6 v12] 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 in a VG that also
has cachevol or integrity volumes will fail to boot.

These patches are also available attached and at
https://github.com/byteit101/grub2/commits/grub-lvmintegrity/

This is identical to the previous version, except patch 3 has been
split into patches 3,4, and 5.

Patrick Plenefisch (6):
  disk/lvm: Make cache_lv more generic as ignored_feature_lv
  disk/lvm: Remove unused cache_pool
  lvm: Match all lvm segments before validation
  lvm: Add support for integrity lv
  lvm: add informational messages in error cases of ignored features
  lvm: Add support for cachevol lv
