[PATCH 1/6 v12] disk/lvm: Make cache_lv more generic as ignored_feature_lv

This patch isn't necessary by itself, but when combined with the next two patchs it enhances readability as ignored_features_lv is then used for multiple types of extra LV's, not just cache LV's Signed-off-by: Patrick Plenefisch Reviewed-by: Daniel Kiper --- grub-core/disk/lvm.c | 176 +

[PATCH 6/6 v12] lvm: Add support for cachevol lv
