Hi Alasdair What are plans in supporting barriers in device mapper? Sometime back Andi Kleen posted a patch[1] to support barriers for single- device dm-devices. Recently Milan Broz posted an RFC patch-set[2] to implement full-barrier support. Are we going to get full-barrier support soon? If not, I would like to see Andi's patch being merged till we get full barrier support ready. I would like to know your thoughts.
