That I would have prefered to see subsys_exit in front of
subsys_initcall instead of module_exit because
1) it made me wonder if it still works in the module case
2) If you see the comment in init.h (/* Don't use these in modules,
but some people do... */), you should not use it in module. The comment
is, at least misleading, because for code that can be used as module or
directly embedded in some cases you are indeed forced to use it (did a
grep and found a lot)
3) Non symetrical code frequently points to errors or bad design.
YMMV :-)
4) If someone someday find something to do when shutting down
(hotrestart, fault tolerance, or something equivalent), we would have a
place to hook. C++ has destructors called after main and before __exit...
NB : This has nothing to do with the proposed patch that is definitively
correct given current init.h.
Personally, I would certainly add:
#define subsys_exit(fn) in init.h
But would rate it myself as a cosmetic change as it *only* makes the code more obvious to read :-)
