So in the latestest patch this has evolved to:
%pAa - print the 'atomic_t' count in decimal
%pAk - print the 'struct kref' count in decimal
%pAr - print the 'refcount_t' count in decimal
... are you still hating it?

We could use a somewhat logical letter for atomic64_t too:
%pAA - print the 'atomic64_t' count in decimal
... as 'A' is the bigger version of 'a', just like atomic64_t is the bigger
version of atomic_t! ;-)

It's a bit more work, but we could do that too, if you still don't like the above
single letter abbreviations.
Thanks,
