From 9a9ebf8cd72b809405ad571fb2f635ffc9df2420 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Mon, 7 Sep 2020 15:09:14 +0300 Subject: RDMA: Restore ability to fail on AH destroy Like any other IB verbs objects, AH are refcounted by ib_core. The release of those objects are controlled by ib_core with promise that AH destroy can't fail. Being SW object for now, this change makes dealloc_ah() to behave like any other destroy IB flows.
