Subject: Re: [PATCH] net: atheros: switch from 'pci_' to 'dma_' API

From: Christophe JAILLET <>

> The wrappers in include/linux/pci-dma-compat.h should go away.
> The patch has been generated with the coccinelle script below and has been
> hand modified to replace GFP_ with a correct flag.
> It has been compile tested.
> When memory is allocated in 'atl1e_setup_ring_resources()' (atl1e_main.c),
> 'atl1_setup_ring_resources()' (atl1.c) and 'atl2_setup_ring_resources()'
> (atl2.c) GFP_KERNEL can be used because it can be called from a .ndo_open.
> 'atl1_setup_ring_resources()' (atl1.c) can also be called from a
> '.set_ringparam' (see struct ethtool_ops) where sleep is also allowed.
> Both cases are protected by 'rtnl_lock()' which is a mutex. So these
> function can sleep.
