Add dm-writecache support
dm-writecache is used like dm-cache with a standard LV
as the cache.
$ lvcreate -n main -L 128M -an foo /dev/loop0
$ lvcreate -n fast -L 32M -an foo /dev/pmem0
$ lvconvert --type writecache --cachepool fast foo/main
$ lvs -a foo -o+devices
LV VG Attr LSize Origin Devices
[fast] foo -wi------- 32.00m /dev/pmem0(0)
main foo Cwi------- 128.00m [main_wcorig] main_wcorig(0)
