* netns xfrm: lookup in netnsAlexey Dobriyan2008-11-2522-67/+75
| | | | | | | | | | Pass netns to xfrm_lookup()/__xfrm_lookup(). For that pass netns to flow_cache_lookup() and resolver callback. Take it from socket or netdevice. Stub DECnet to init_net. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Instead of further increasing the #ifdeffery in this function, restructure the code a bit and get rid of the #ifdef. This relies on the fact that pci_enable_msi() will always fail in the !CONFIG_PCI_MSI case. There should be no change in driver behavior.

The compiler does not recognize the relation between "value" and "mandatory" variables: the code flow can ever reach the "out_invalid_option:" label if 'mandatory' is set to 1, and when 'mandatory' is non-zero, we'll always have 'value' initialized.

But even if ->rx_ring_num is nonzero, 'err' will be zero if mlx4_en_fill_rx_buffers() fails and mlx4_en_activate_rx_rings() returns success - incorrectly.
