Ulrich Drepper points out that EPOLL_CTL_DEL doesn't need to copy any of
the hash events.

Also, we should specify in the man pages that a NULL is allowed in
EPOLL_CTL_DEL.  Currently it does not say that. 

Also, starting from when epoll uses rbtrees instead of hashes, the
'size' hint passed to epoll_create(2) is no more used.  But since an API
change has clearly to be excluded, I guess it'll stay as is.

Now that we are correctly kicking off kswapd early (before the synch
reclaim watermark), it is really doing asynchronous pageout.  This has
exposed a latent problem where allocators running at the same time will
make kswapd think it is getting into trouble, and cause too much swapping
and suboptimal behaviour.

This patch changes the kswapd scanning algorithm to use the same metrics
for measuring pageout success as the synchronous reclaim path - namely, how
much work is required to free SWAP_CLUSTER_MAX pages.

This should make things less fragile all round, and has the added benefit
that kswapd will continue running so long as memory is low and it is
managing to free pages, rather than going through the full priority loop,
then giving up.  Should result in much better behaviour all round,
especially when there are concurrent allocators.
