Hi Roland,
These two patches add memory region re-registration support.
Memory re-registration is a feature that enables one to change
the attributes of a memory region, including PD, translation
(address and length) and access flags.
The first patch changes the API between libibverbs and the provider's
library. This change is safe as there's no ibv_rereg_mr verb exposed to
the user and thus no reason for a vendor to implement or use this function.
The second patch adds the actual memory region re-registration support.
