I've posted something similar to this before (I believe it used inline
functions which have the nasty side effect of code bloat for multiple
modules) to trim down the module to supply only the code it cares about.
This preserves the module's ability to explicitly implement each hook
(IOW, no magic defaults).
Some stats:
text data bss dec hex filename
before 4373 640 4 5017 1399 capability.o
after 2181 640 4 2825 b09 capability.o
before 1713 0 4 1717 6b5 security.o
after 1791 0 4 1795 703 security.o
The patch below exports two new functions. The (void *) cast-o-rama is
to kill compiler warnings. If we really wanted to bother Greg, we could
create a series of typedefs for casting ;-)
typedef int (*sethostname_t) (char *hostname);
.sethostname = (sethostname_t)lsm_return_ok,
thanks,
