Subject: [PATCH] net: ethernet: et131x: Use GFP_KERNEL instead of GFP_ATOMIC when allocating tx_ring->tcb_ring
Date: Wed, 31 Jul 2019 09:38:42 +0200 [thread overview]
Message-ID: <20190731073842.16948-1-christophe.jaillet@wanadoo.fr> (raw)
There is no good reason to use GFP_ATOMIC here. Other memory allocations
are performed with GFP_KERNEL (see other 'dma_alloc_coherent()' below and
'kzalloc()' in 'et131x_rx_dma_memory_alloc()')
Use GFP_KERNEL which should be enough.
