Hi Hackers,
I wanted to share with you some work I've been doing for a couple of
months with the spin verifier and OS C code. [1]
Although not directly and immediately relevant to current kernel
development, this may be relevant to folks thinking about architecture
and future directions in managi

The objpool_push can only happen on local cpu node, so only the local
cpu can touch slot->tail and slot->last, which ensures the correctness
of using cmpxchg without lock prefix (using try_cmpxchg_local instead
of try_cmpxchg_acquire).
Testing with IACA found the lock version of pop/push pair cost
As kernel test robot reported, lib/test_objpool.c (trace:probes/for-next)
has linux/version.h included, but version.h is not used at all. Then more
unused headers are found in test_objpool.c and rethook.c, and all of them
should be removed.

The failure path of allocating ei goes to a path that dereferences ei.
Add another label that skips over the ei dereferences to do the rest of
the clean up.
