You should add a section where you enable your code in the proper
Kconfig file (eg. net/Kconfig)
config NSPATCH
...
...
...
In net/core/sock.c use:
#if CONFIG_NSPATCH
#endif
By the way, patches with ifdef in the .c files are not accepted in
mainline. You should create in the corresponding header file:
#ifdef CONFIG_NSPATCH
int nspatch_function(int dummy);
#else
static inline int nspatch_function(int dummy)
{
return 0;
}
#endif
Please refer to the CodingStyle file in the Documentation directory for
more informations.
