nfs4_purge_state_owners(9)

💅 nfs4_purge_state_owners(9) 💅

okay so bestie, you're looking at a page from the Kernel API Manual, section 9, and the function is literally called nfs4_purge_state_owners. yes. we're doing kernel internals today. put your hair up. 🎀

---

✨ NAME ✨

nfs4_purge_state_owners — release all the cached state owners. all of them. every last one. no crumbs. 🧹

---

🌸 SYNOPSIS 🌸

void nfs4_purge_state_owners (struct nfs_server *server , struct
       list_head *head );

like, that's the whole signature. she's a void, she returns nothing, she simply does. main character energy fr fr. 👑

---

🦋 ARGUMENTS 🦋

• server — the nfs_server holding all those cached state owners you're about to release. yes, that one. 🖥️
• head — the resulting list of state owners. this is where they all end up. think of it as the group chat they get yeeted into. 📋

---

💖 DESCRIPTION 💖

so this one gets called at umount time. 🫶

by then, the remaining state owners are chilling on the LRU with a ref count of zero. zero. nada. they're giving ghosted-by-the-refcount energy. 👻

⚠️ important caveat bestie, don't miss this: the state owners are not freed here. they're just added to the list head, which you can later use as an argument to nfs4_free_state_owners. so this is the staging step, not the cleanup step. the actual free happens somewhere else. iykyk. 💀

like, read that again if you need to — nfs4_purge_state_owners purges ownership, not memory. different vibes entirely. ✨
