[net-next][PATCH v2] RDS: Make user visible data types consistent with rest of the kernel

From: Santosh Shilimkar
Date: Mon Feb 20 2017 - 17:17:24 EST


Use "__uX/__sX" kernel types rather than current uint*/int* for
entire file.

v1->v2:
As suggested by David Miller, cleaned up entire header to use kernel types.
