The patch you're discussing is intended to stop processes that would dirty many pages from filling up memory with dirty pages far faster than the device can emit them, and only then blocking; instead it forces them to block sooner, before so much of memory is filled up by its dirtied pages.
This is orthogonal to the patch under discussion, which is arranging that when something *has* filled memory and then freed it all again, that useful stuff gets put back in there sooner rather than later: after all, memory can be filled by many things other than dirtied pages awaiting flushing (e.g., large ld(1) runs ;) )
