Date: Tue, 10 Aug 2021 20:53:14 +0800 From: Yang Yingliang <yangyingliang@...wei.com> To: <linux-kernel@...r.kernel.org>, <linux-staging@...ts.linux.dev> CC: <Larry.Finger@...inger.net>, <phil@...lpotter.co.uk>, <gregkh@...uxfoundation.org> Subject: [PATCH -next] staging: r8188eu: Use GFP_ATOMIC under spin lock A spin lock is taken in __nat25_db_network_insert() and update_BCNTIM() is called under spin lock so we should use GFP_ATOMIC in both place.
