Subject: [PATCH mm-unstable v3 0/6] mm/mglru: performance optimizations

This series improves performance for some previously reported test
cases. Most of the code changes gathered here has been floating on the
mailing list [1][2]. They are now properly organized and have gone
through various benchmarks on client and server devices, including
Android, FIO, memcached, multiple VMs and MongoDB.

In addition to the warning [3] fixed in v2, this version fixes another
warning [4] reported by syzbot.
