It's fine with me if the morning session considers IO-less dirty throttling with block cgroup service differentiation, but defers memcg aspects to 12:30. > We've been discussing about how to combine IO-less throttling and memcg > awareness of the writeback and Greg was designing some framework to do > this... Greg? My initial patches are between memcg and the current IO-full throttling code. However, the framework ideally will also allow for IO-less dirty throttling with memcg. I have not wrapped my head around how this should work with block cgroup isolation. I am hoping others can help out with the block aspects. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
