Well, either not break the line really (it's just trivially 
above col80: it's 83 cols), or do a *sensible* line break - one 
of:

static void timekeeper_xtime_add(struct timekeeper *tk,
				 const struct timespec *ts)

(here the arguments align vertically)

Or:

static void
timekeeper_xtime_add(struct timekeeper *tk, const struct timespec *ts)

(here he return type is on a separate line)

Or, my favorite, just make the name shorter, because it's too 
long:

static void tk_xtime_add(struct timekeeper *tk, const struct timespec *ts)

Obviously this applies to other functions as well - the tk_*() 
method pattern should be applied consistently. Anyone reading 
time code will know that 'tk' is about the global timekeeper 
structure - no need to use the verbose name in methods.

Thanks,

	Ingo
