💖 fscache_acquire_cache(9) 💖

okay bestie, this is straight from the Kernel API Manual and it’s literally about acquiring a cache-level cookie. slay. 🍪✨

✨ NAME ✨

fscache_acquire_cache — Acquire a cache-level cookie.

---

🌸 SYNOPSIS 🌸

struct fscache_cache * fscache_acquire_cache (const char *name );

---

🎀 ARGUMENTS 🎀

• name — the name of the cache. that’s the whole vibe, no cap.

---

🦋 DESCRIPTION 🦋

The main character move here is: get a cookie to represent an actual cache. 💅

If a name is given and there is a nameless cache record available, this will acquire that record and set its name, directing all the volumes using it to this cache. periodt. 🔥

The cache will be switched over to the preparing state if it’s not currently in use. otherwise -EBUSY will be returned. 😭

heads up bestie: if it is currently in use, you get -EBUSY instead of the switch. no cap.
