Subject: [PATCH 5/5] crypto: engine: check if BH is disabled during completion
Date: Mon, 21 Feb 2022 12:08:33 +0000	[thread overview]
Message-ID: <20220221120833.2618733-6-clabbe@baylibre.com> (raw)
In-Reply-To: <20220221120833.2618733-1-clabbe@baylibre.com>

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.
