[GIT PULL 0/5] IPVS Updates for v4.18

[Simon Horman <horms@verge.net.au>]

Hi Pablo,

please consider these IPVS enhancements for v4.18.

* Whitepace cleanup

* Add Maglev hashing algorithm as a IPVS scheduler

  Inju Song says "Implements the Google's Maglev hashing algorithm as a
  IPVS scheduler.  Basically it provides consistent hashing but offers some
  special features about disruption and load balancing.

  1) minimal disruption: when the set of destinations changes,
     a connection will likely be sent to the same destination
     as it was before.

  2) load balancing: each destination will receive an almost
     equal number of connections.

 https://www.usenix.org/system/files/conference/nsdi16/nsdi16-paper-eisenbud.pdf
 "

* Fix to correct implementation of Knuth's multiplicative hashing
  which is used in sh/dh/lblc/lblcr algorithms. Instead the
  implementation provided by the hash_32() macro is used.
