Subject: tools: remove atomic_set_release() usage in tools/
Date: Sun, 16 Feb 2025 21:43:51 -0800
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.
