Ok, I'll check it. Maybe I miss !CONFIG_SWAP...
v4 here. Thank you for pointing out. I could think of several ways but
maybe this one is good because using vm_swappines with !CONFIG_SWAP seems
to be a bug.
No, it isn't a bug - swappiness also controls the kernel's eagerness to
unmap and reclaim mmapped pagecache.
Oh, really ? I didn't understand that.
Hmm, anyway, this new version of fix seems better.
