Merge tag 'ipvs-for-v4.18' of http://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-next
Simon Horman says:
====================
IPVS Updates for v4.18
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.
Seel also: [3.4 Consistent Hasing] in
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.
