Subject: [PATCH] net/mlx5e: kTLS, Fix GFP_KERNEL in spinlock context
Date:   Thu, 3 Sep 2020 19:45:34 +0800
Message-ID: <1599133539-175203-1-git-send-email-xuwei5@hisilicon.com>

Precedence: bulk

Replace GFP_KERNEL with GFP_ATOMIC while resync_post_get_progress_params
is invoked in a spinlock context.
This code was detected with the help of Coccinelle.
