FYI
The first failure seems to be a confusion between function declarations and definitions - eg for linux-2.6.7, it says FsmNew() is called by drivers/isdn/hisax/fsm.h::CallcNew, thus:
$cscope -d -p9 -L -3 FsmNew ... drivers/isdn/hisax/fsm.h CallcNew 50 int FsmNew(struct Fsm *fsm, struct FsmNode,*fnlist, int fncount); ...
but there is no call there, only an external declaration of FsmNew, and no declaration of CallcNew of any kind whatsoever in that file!
The second failure appears to be related to an inability to cope with complicated declarations within a prototype, such of those of type pointer-to-function. For example, the definition:
struct net_device *alloc_netdev(int sizeof_priv, const char *mask, void (*setup)(struct net_device *))
from line 73 of drivers/net/net_init.c, is not recognized by cscope as a valid function definition and so it does not find the call to kmalloc (or anything else) contained in that function.
$ cscope -d -p9 -L -1 alloc_netdev <nothing> $ cscope -d -p9 -L -3 kmalloc | grep alloc_netdev <nothing>
