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.

Including unnecessary headers doesn't sound right.

I've removed the unused functions and added the statics.
Thanks,

They aren't unnecessary.
If you #include them, gcc can tell when the prototypes in the header and
the C file are accidentially different.
Without the #include's, this would result in a nasty runtime error.

your answer.
