Subject: [PATCH net-next 1/7] page_pool: add page_pool_dev_alloc_netmem()
Date: Wed, 18 Dec 2024 18:44:29 +0100	[thread overview]
Message-ID: <20241218174435.1445282-2-aleksander.lobakin@intel.com> (raw)
In-Reply-To: <20241218174435.1445282-1-aleksander.lobakin@intel.com>

Similarly to other _dev shorthands, add one for page_pool_alloc_netmem()
to allocate a netmem using the default Rx GFP flags (ATOMIC | NOWARN) to
make the page -> netmem transition of drivers easier.
