From 8b7b59d030cc0d34b83b0c556bb6365c9ae6ba77 Mon Sep 17 00:00:00 2001 From: Zhu Yanjun Date: Sun, 19 Aug 2018 15:04:01 +0800 Subject: IB/rxe: remove redudant qpn check In the commit 536ca245c512 ("IB/rxe: Drop QP0 silently"), if qpn is zero, the function directly returns. So in the following function, it is not necessary to check qpn. The qpn check in the function check_keys is removed.
