Subject: [PATCH 1/1] fixup! tools: remove atomic_set_release() usage in tools/

Userspace versions of both atomic_set_release() and atomic_set() get
translated into uatomic_set(). To avoid extra definitions of
atomic_set_release(), replace its usage inside refcount_set_release()
with atomic_set(). This results in no functional changes.

Fixes: 1465347e498f ("mm: make vma cache SLAB_TYPESAFE_BY_RCU")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202502170049.sHfzQwpv-lkp@intel.com/
