The usage question about memory.kmem.limit_in_bytes

Asked by Cui Wei on 2016-04-10

After upgrading kernel from 4.2 to 4.4, I found out that both "memory.kmem.limit_in_bytes" and "memory.kmem.usage_in_bytes" become unusable: the former one cann't be written and the latter is also read with 0 value.

I want to ask the question that whether there will be no kmem any more, in other words:

If i set a the value of "memory.memsw.limit_in_bytes" to 4G, and set the value of "memory.limit_in_bytes" to 0G,

then whether the whole memory data of its controlled processes will be totally moved to swap disk?
