From 4058cf08945c18a6de193f4118fd05d83d3d4285 Mon Sep 17 00:00:00 2001 From: Corentin Labbe Date: Mon, 21 Feb 2022 12:08:33 +0000 Subject: crypto: engine - check if BH is disabled during completion When doing iperf over ipsec with crypto hardware sun8i-ce, I hit some spinlock recursion bug. This is due to completion function called with enabled BH. Add check a to detect this.
