Hi Julia,
I'm trying to generate a patch to define a function with different
arguments depending on the kernel version. I'm having some difficulties,
maybe you can tell me what's wrong with the following approach.
@ rule1 @
struct net_device_ops ops;
identifier vlan_rx_add_vid_func;
@@
ops.ndo_vlan_rx_add_vid = vlan_rx_add_vid_func;
@ rule2 @
identifier rule1.vlan_rx_add_vid_func;
expression a,b,c;
@@
+#if LINUX_VERSION_CODE >= KERNEL_VERSION(3,10,0)
vlan_rx_add_vid_func(a, b, c)
+#else
+ vlan_rx_add_vid_func(a, c)
+#endif
This results in
spatch --sp-file test3.cocci drivers/net/ethernet/intel/igb/igb_main.c
init_defs_builtins: /usr/local/share/coccinelle/standard.h
282 302
Fatal error: exception Failure("plus: parse error:
= File "test3.cocci", line 14, column 2, charpos = 282
around = 'vlan_rx_add_vid_func', whole content = + vlan_rx_add_vid_func(a,
c)
")
If I remove "vlan_rx_add_vid_func(a, c)" it works, but that defeats the
whole idea.
Thanks!
Stefan
