There's no need to ifdef them out; in include/proc_fs.h there are the
following convenience #define's if CONFIG_PROC_FS is not defined:
#define remove_proc_entry(name, parent) do {} while (0)
static inline struct proc_dir_entry *proc_symlink(const char *name,
struct proc_dir_entry *parent,const char *dest) {return NULL;}
static inline struct proc_dir_entry *proc_mkdir(const char *name,
struct proc_dir_entry *parent) {return NULL;}
static inline struct proc_dir_entry *create_proc_read_entry(const char *name,
mode_t mode, struct proc_dir_entry *base,
read_proc_t *read_proc, void * data) { return NULL; }
static inline struct proc_dir_entry *create_proc_info_entry(const char *name,
mode_t mode, struct proc_dir_entry *base, get_info_t *get_info)
{ return NULL; }
Adding the #ifdef's just makes the code look ugly, and for no purpose,
since the compiler will take care of removing the code for us.
