memcg: update maintainers

More players joined to memory cgroup developments and Johannes' great work
changed internal design of memory cgroup dramatically.  And he will do
more works.  Michal Hokko did many bug fixes and know memory cgroup very
well.  Daisuke Nishimura helped us very much but he seems busy now.
Thanks to his works.

CREDITS: update Kees's expired fingerprint and fix details

Small clean-up for my CREDITS entry; the GPG fingerprint was not up to
date, so I fixed other details at the same time too.

thp: reduce khugepaged freezing latency

Use wait_event_freezable_timeout() instead of
schedule_timeout_interruptible() to avoid missing freezer wakeups.  A
try_to_freeze() would have been needed in the khugepaged_alloc_hugepage
tight loop too in case of the allocation failing repeatedly, and
wait_event_freezable_timeout will provide it too.

khugepaged would still freeze just fine by trying again the next minute
but it's better if it freezes immediately.

vmscan: use atomic-long for shrinker batching

Use atomic-long operations instead of looping around cmpxchg().

vmscan: fix initial shrinker size handling

A shrinker function can return -1, means that it cannot do anything
without a risk of deadlock.  For example prune_super() does this if it
cannot grab a superblock refrence, even if nr_to_scan=0.  Currently we
interpret this -1 as a ULONG_MAX size shrinker and evaluate `total_scan'
according to this.  So the next time around this shrinker can cause really
big pressure.  Let's skip such shrinkers instead.

Also make total_scan signed, otherwise the check (total_scan < 0) below
never works.
