ecryptfs_ac...free_msg_ctx(9)

✨ ecryptfs_ac...free_msg_ctx(9) ✨

okay bestie so this is a page from the Kernel API Manual, and like… the name is a whole mouthful. The function is literally called ecryptfs_acquire_free_msg_ctx (yes, the header squishes it to ecryptfs_ac...free_msg_ctx(9) — she's dramatic, she abbreviates) 💅

🎀 NAME 🎀

ecryptfs_acquire_free_msg_ctx —

no cap, the manual page genuinely just trails off there. Nothing after the dash. The void. The silence. Honestly? Iconic. 🫥

---

🌸 SYNOPSIS 🌸

int ecryptfs_acquire_free_msg_ctx (struct ecryptfs_msg_ctx **msg_ctx );

---

🦋 ARGUMENTS 🦋

• msg_ctx — the context that was acquired from the free list. That's the whole vibe: it's a pointer-to-a-pointer, and it's where the freshly-grabbed context ends up 🎀

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this function acquires a context element from the free list and then locks the mutex on the context. Two things. Both slay.

Then it sets the msg_ctx task to current. Like, it claims it. main character assignment, fr fr 👑

Returns zero on success; non-zero on error or upon failure to acquire a free context element. So basically zero = we ate, non-zero = we did not eat 😭

⚠️ big important caveat bestie: this must be called with ecryptfs_msg_ctx_lists_mux held. Not optional. Not a suggestion. Hold the mux. 🫶
