From 299c36b1efe7a34ff255788592d835e913163a4d Mon Sep 17 00:00:00 2001 From: Kamal Heib Date: Thu, 5 Jul 2018 00:52:47 +0300 Subject: [PATCH] RDMA/ipoib: Use min_t() macro instead of min() Use min_t() macro to avoid the casting when using min() macro, also fix the type of "length" and "wc->byte_len" to be "unsigned int" and "u32" which is the right type for each one of them.
