Your most recent kernel with cgroup_disable=memory shows no swap usage when copying 16GB of data between drives.

Thanks! Do you happen to use memory cgroups controller intentionally or it is being used automagically? I suspect the later. As already mentioned earlier (comment 12) the global memory pressure is spread over all existing memory cgroups. Anyway, your earlier tests suggested that cgroup_disable on its own didn't help and we need to have the 2 patches reverted. I will mull over some more but I unless Vlastimil or Mel oppose I will go ahead and revert both in 15sp2 and openSUSE-15.2 branches. For a better experience with cgroups enabled I would recommend using a most recent kernel (e.g. one from our stable repository). -- You are receiving this mail because: You are the assignee for the bug.
