[PATCH krping 0/2] krping fixes to work with latest kernels

[Or Gerlitz]

Hi Steve,

This little series from Alex makes krping from git://git.openfabrics.org/~swise/krping.git
usable for latest upstream kernels, something we find very useful for testing
the upstream RDMA stack when developing variuos features.

Or.

Hi,
Also credit should be given to Roi Dayan (roid-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org) - it was our joint work.

Thank you,
