ntb_msg_clear_sts(9)

✨ NAME ✨

ntb_msg_clear_sts — clears the status bits of the message registers, bestie 💅

okay so real talk, this page lives in the Kernel API Manual, section 9, and it's one of those tiny-but-iconic kernel helpers 💖 if you're reading this you're already deep in NTB land, so let's go 🦋

---

🌸 SYNOPSIS 🌸

int ntb_msg_clear_sts (struct ntb_dev *ntb , u64 sts_bits );

that's the whole call, no cap ✨

---

🎀 ARGUMENTS 🎀

• ntb — the NTB device context 🫶 like, the device you're doing the thing to.
• sts_bits — the status bits you wanna clear 💅 you pick which ones, that's the whole job.

---

🦋 DESCRIPTION 🦋

Clear bits in the status register ✨

that's it, that's the vibe. it's giving "small function, big responsibility" 👑

---

🔥 RETURN 🔥

Zero on success 💖 otherwise a negative error number 😭 (so fr fr, check it).
