[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH] YA trivial patch: statics, remove check_region, remove pci/compat.c
Some functions aren't static and could be (damn C language!).
I tried turning on -Wmissing-prototypes: unfortunately gives warnings
for functions used in asm, which means introducing gratuitous prototypes
for them. Not sure it's worth it.
1) keyhandler.c: keypress_softirq() and do_task_queues() can be static.
2) physdev.c: pcidev_dom0_hidden() can be static.
3) resource.c/resource.h: check_region is deprecated (racy): remove.
4) sched_bvt.c: lots of things can be static.
5) pci/compat.c: not required for Xen.
