Subject: [PATCH net-next 01/11] s390/qeth: use memory reserves to back RX buffers
Date: Wed, 18 Mar 2020 13:54:45 +0100	[thread overview]
Message-ID: <20200318125455.5838-2-jwi@linux.ibm.com> (raw)
In-Reply-To: <20200318125455.5838-1-jwi@linux.ibm.com>

Use dev_alloc_page() for backing the RX buffers with pages. This way we
pick up __GFP_MEMALLOC.
