I get more than that on linux-next:
include/linux/proc_fs.h:58:20: error: redefinition of 'proc_set_size'
include/linux/proc_fs.h:51:20: note: previous definition of 'proc_set_size' was here
include/linux/proc_fs.h: In function 'proc_net_mkdir':
include/linux/proc_fs.h:69:2: error: implicit declaration of function 'proc_mkdir_data' [-Werror=implicit-function-declaration]
include/linux/proc_fs.h:69:2: warning: return makes pointer from integer without a cast [enabled by default]
so don't we need to do this instead?
