Daniel Borkmann 87545899b5 net: replace remaining users of arch_fast_hash with jhash ... This patch effectively reverts commit 500f808726 ("net: ovs: use CRC32 accelerated flow hash if available"), and other remaining arch_fast_hash() users such as from nfsd via commit 6282cd5655 ("NFSD: Don't hand out delegations for 30 seconds after recalling them.") where it has been used as a hash function for bloom filtering. While we think that these users are actually not much of concern, it has been requested to remove the arch_fast_hash() library bits that arose from [1] entirely as per recent discussion [2]. The main argument is that using it as a hash may introduce bias due to its linearity (see avalanche criterion) and thus makes it less clear (though we tried to document that) when this security/performance trade-off is actually acceptable for a general purpose library function. Lets therefore avoid any further confusion on this matter and remove it to prevent any future accidental misuse of it. For the time being, this is going to make hashing of flow keys a bit more expensive in the ovs case, but future work could reevaluate a different hashing discipline.
