The patch still cleanly applies to linux-next as wells as Linus's tree.
Some %pf bits have appeared and fixed since (include/trace/events/timer.h);
the fix is in linux-next so once that and this patch are merged, there are
no remaining %pf (or %pF) users left.
The original patch:
<URL:https://lore.kernel.org/lkml/tip-6849cbb0f9a8dbc1ba56e9abc6955613103e01e3@git.kernel.org/>
The fix:
