From d659f9f60f6a119654c65bfa58aa6fa762c0824d Mon Sep 17 00:00:00 2001 From: Yufeng Mo Date: Mon, 29 Jul 2019 10:53:25 +0800 Subject: [PATCH] net: hns3: change GFP flag during lock period When allocating memory, the GFP_KERNEL cannot be used during the spin_lock period. This is because it may cause scheduling when holding spin_lock. This patch changes GFP flag to GFP_ATOMIC in this case.
