Thinking about this I'm not sure we have no leftovers that are doing the hide-unhide dance on their own, behind p2sb_bar()'s back. But the idea is that all drivers that need this functionality in the kernel have to work through p2sb_bar() entry point. If any problem is found in the future with that, those will need to be fixed separately. -- With Best Regards, Andy Shevchenko
