Hi This is the series of 14 patches for barriers. This is the "correct" implementation --- i.e. enabling barriers for any targets. These patches address the upper layer only (providing barriers to filesystem), they don't send barrier request (there will be more patches for that, but they are not yet finalized). The patches are sorted from the simples to the more complicated. The first 11 patches shouldn't have effect on anything, they just move code around. So you can start slowly applying them. Patch 11 changes generic block layer code, other patches change only dm. Mikulas -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
