Hi, here are 5 patches that remove 4 members from struct scan_control. sc->may_unmap is no longer used after patch #1, sc->may_swap is folded into sc->swappiness, sc->all_unreclaimable is made a return value, and sc->isolate_pages is replaced with a branch on sc->mem_cgroup (reusing a nearby branch, so no additional one) and direct function calling. So nothing too spectecular. It saves a bit of code and 2 to 4 stack words depending on the wordsize and call path.
