__releases_shared(9)

💅 __releases_shared — NAME

ok so bestie, gather round: __releases_shared is a function attribute, and what it declares is that the function releases a context lock shared. That's the whole vibe. It's from the Kernel API Manual, and yes it's exactly as niche and iconic as it sounds.

✨ SYNOPSIS ✨

__releases_shared (... );

🎀 ARGUMENTS 🎀

• ... — variable arguments. literally just vibes in vararg form, that's the whole list 🫶

🌸 DESCRIPTION 🌸

okay so here's the tea ☕ — this is a function attribute that declares the function releases the given context lock instance(s) with shared access.

and the important part, the part you cannot skip, the part that's giving rules: the associated context(s) must be active on entry. no cap. if they're not active when you go in, that's a you problem, not a doc problem 😭
