svc_serv_nrpools(9)

✨ svc_serv_nrpools(9) ✨

okay so bestie, welcome to svc_serv_nrpools(9) from the Kernel API Manual 🎀 this one is short, sweet, and lowkey iconic — no cap.

---

💅 NAME 💅

svc_serv_nrpools — number of thread pools backing a service

---

🫶 SYNOPSIS 🫶

unsigned int svc_serv_nrpools (const struct svc_serv *serv );

---

🎀 ARGUMENTS 🎀

• serv — An RPC service

---

💖 DESCRIPTION 💖

Pooled services all share the global svc_pool_map, so their pool count is svc_pool_map.npools. Unpooled services have a single pool. Reading npools without svc_pool_map_mutex is safe: a pooled service holds a map reference for its whole lifetime, so npools is stable once set.

Return value: the number of pools in serv ✨
