eventfd_ctx_put(9)

💅 eventfd_ctx_put

okay so bestie, welcome to the Kernel API Manual — yes, the kernel has man pages too, we're literally in eventfd_ctx_put(9) territory and it's giving very much "clean up after yourself" energy. ✨

---

🌸 NAME

eventfd_ctx_put — releases a reference to the internal eventfd context. that's it, that's the whole job. she's a one-task icon and she ate. 💅

---

🎀 SYNOPSIS

void eventfd_ctx_put (struct eventfd_ctx *ctx );

no return value, no drama, just vibes and a pointer. periodt.

---

✨ ARGUMENTS

• ctx — [in] pointer to eventfd context. that's your main character right there, hand her over and let her go 🫶

---

🔥 DESCRIPTION

so here's the tea: the eventfd context reference must have been previously acquired — either with eventfd_ctx_fdget or with eventfd_ctx_fileget. like, you can't just put a reference you never got, bestie, that's not how any of this works 😭

real talk: this is a must, not a "would be nice." the reference has to already be yours before you release it. no cap. 🔥
