We don't usually embed '_unlikely' in function names; we just do:
static inline bool slub_debug_enabled(void) { return static_branch_unlikely(&slub_debug_enabled); }
eg:
static inline bool cpusets_enabled(void) { return static_branch_unlikely(&cpusets_enabled_key); }
#define cgroup_bpf_enabled(type) static_branch_unlikely(&cgroup_bpf_enabled_key[type])
static inline int ip_tunnel_collect_metadata(void) { return static_branch_unlikely(&ip_tunnel_metadata_cnt); }
static inline bool frontswap_enabled(void) { return static_branch_unlikely(&frontswap_enabled_key); }
