This patch contains the following possible cleanups:
- every file should #include the headers containing the prototypes for
it's global functions
- make needlessly global functions static
- #if 0 the following unused global functions:
- device.c: dlm_device_free_devices
- lock.c: dlm_remove_from_waiters
- lockspace.c: dlm_find_lockspace_name
Please review which of these changes do make sense.
