From 3fb905f07ea45b31c8f67ba6e4668de46f527e65 Mon Sep 17 00:00:00 2001 From: Jacob Moroni Date: Tue, 1 Sep 2026 16:00:14 +0000 Subject: [PATCH] RDMA/irdma: Enforce local fence for IB_WR_REG_MR Enforce local fence for IB_WR_REG_MR to avoid spurious FASTREG_VALID_MKEY async events during heavy invalidation and registration activity. Commit 69e8e429bca2 ("RDMA/irdma: Enforce local fence for LOCAL_INV WRs") was very similar, but was not sufficient to prevent all occurrences of these async events.
