Hi Dave,
After merging the final tree, today's linux-next build (powerpc
ppc44x_defconfig) failed like this:
net/core/net-sysfs.c:476: warning: 'struct netdev_rx_queue' declared inside parameter list
net/core/net-sysfs.c:476: warning: its scope is only this definition or declaration, which is probably not what you want
net/core/net-sysfs.c:478: warning: 'struct netdev_rx_queue' declared inside parameter list
net/core/net-sysfs.c: In function 'rx_queue_attr_show':
net/core/net-sysfs.c:489: error: dereferencing pointer to incomplete type
net/core/net-sysfs.c:489: warning: type defaults to 'int' in declaration of '__mptr'
net/core/net-sysfs.c:489: warning: initialization from incompatible pointer type
net/core/net-sysfs.c:489: error: invalid use of undefined type 'struct netdev_rx_queue'
net/core/net-sysfs.c:494: warning: passing argument 1 of 'attribute->show' from incompatible pointer type
net/core/net-sysfs.c:494: note: expected 'struct netdev_rx_queue *' but argument is of type 'struct netdev_rx_queue *'
(and many more)
Caused by commit 0a9627f2649a02bea165cfd529d7bcb625c2fcad ("rps: Receive
Packet Steering") from the net tree. struct netdev_rx_queue is protected by
CONFIG_RPS in netdevice.h, but uses are not so protected in net-sysfs.c.
I applied the following patch for today:
