ecryptfs_msg...ree_to_alloc(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ecryptfs_msg_ctx_free_to_alloc(9) 💖

okay so bestie, we're in the Kernel API Manual today and this one is a tiny little function in the Linux kernel's ecryptfs messaging code 🌸 it's short, it's sweet, and it has exactly one rule you cannot break. let's get into it 🎀

✨ NAME ✨

ecryptfs_msg_ctx_free_to_alloc — and that's… literally it 😭 the NAME section just drops the function name and dips, no tagline, no nothing. iconic behaviour honestly 💅 but don't worry, the rest of the page does the explaining for it 🫶

🌈 SYNOPSIS 🌈

void ecryptfs_msg_ctx_free_to_alloc (struct ecryptfs_msg_ctx *msg_ctx );

returns void, takes one pointer, no drama, no return value, no cap ⭐

🎀 ARGUMENTS 🎀

  • msg_ctx — the context you're moving from the free list to the alloc list 🦋 that's the whole job. free list ➡️ alloc list. a little glow-up migration for your message context ✨

💜 DESCRIPTION 💜

so here's the thing, and it is the thing 👑

you MUST call this with ecryptfs_msg_ctx_lists_mux held. like, held already. by you. before you call this. it does not do it for you 💀

that's the entire caveat and it's not optional — the manual says "must" and the manual means it 🙈 so grab that mutex first, then call away, bestie 🧚

🔥 SEE ALSO 🔥

the kernel file lives at ./fs/ecryptfs/messaging.c 📁 and while you're in there, go say hi to the whole friend group:

like a whole group chat of message-context functions, and this one is the lowkey one that just shuffles things between lists 🍓

and that's the page!! mwah 💋 this lil beauty comes to you from ./fs/ecryptfs and it's dated October 2026 — put it in your calendar, frame it, whatever, it's giving vintage ✨👑 see u in the next manpage bestie 🫶💖
