[PATCH mm-unstable v2 0/6] mm/mglru: performance optimizations

[Yu Zhao]

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.

This v2 mainly fixes a warning reported by syzbot [3].
