That is the bug fixed by the patch linked in this one's notes: https://lore.kernel.org/linux-trace-kernel/[email protected]/ It removes the reference count so __destroy_hist_field() frees unconditionally, and the three-reference case no longer leaks. The two patches are independent and apply in either order.
