ecryptfs_msg...lloc_to_free(9)

🌸 ecryptfs_msg_ctx_alloc_to_free(9) — the Kernel API Manual, bestie edition 🌸

okay so you found the section 9 page for ecryptfs_msg_ctx_alloc_to_free, and honestly? it's a tiny little legend 💅 it does exactly one thing and it does it under a lock, periodt.

✨ NAME ✨

ecryptfs_msg_ctx_alloc_to_free — and that's literally it, the manpage gives us no description line after the dash 😭 so we're going with the vibes only: it's the function that moves a msg_ctx from the alloc list over to the free list. no cap, that's the whole personality.

---

🦋 SYNOPSIS 🦋

void ecryptfs_msg_ctx_alloc_to_free (struct ecryptfs_msg_ctx *msg_ctx );

it returns void, so don't go looking for a return value, she gives you nothing back and that's iconic 👑

---

🎀 ARGUMENTS 🎀

• msg_ctx — the context to move from the alloc list to the free list. that's the whole argument list, one (1) pointer, we love a low-maintenance function 🫶

---

🧚 DESCRIPTION 🧚

okay this is the important part and it's short but it's highkey serious:

Must be called with ecryptfs_msg_ctx_lists_mux held.

like, fr fr, that's the requirement. you gotta be holding ecryptfs_msg_ctx_lists_mux when you call this. no lock, no call, that's the rule bestie 🙈 it's giving "read the room before you touch the lists" energy.
