Subject: [PATCH 2/6] workqueue: Remove GPF argument from alloc_workqueue_attrs()
Date: Thu, 13 Jun 2019 16:50:23 +0200	[thread overview]
Message-ID: <20190613145027.27753-3-bigeasy@linutronix.de> (raw)
In-Reply-To: <20190613145027.27753-1-bigeasy@linutronix.de>

From: Thomas Gleixner <tglx@linutronix.de>

All callers use GFP_KERNEL. No point in having that argument.
