📦 version 7.3.1, in nixpkgs unstable

💅 ntb_msg_clear_mask — from the Kernel API Manual, bestie

Okay so picture this: you're deep in kernel-land, the manual you're reading is literally called the Kernel API Manual, and today's main character is ntb_msg_clear_mask. She's small, she's focused, she clears bits. That's the whole vibe. Let's get into it 🎀

✨ NAME ✨

ntb_msg_clear_mask — clears the mask on the message registers, periodt 💅

🌸 SYNOPSIS 🌸

int ntb_msg_clear_mask (struct ntb_dev *ntb , u64 mask_bits );

Look at her. Two arguments. No drama. Iconic ✨

🦋 ARGUMENTS 🦋

  • ntb — the NTB device context, aka your little handle on the NTB device you're messing with 🫶
  • mask_bits — the mask bits you want to clear, fr fr

💖 DESCRIPTION 💖

So what she actually does: she clears bits in the message events mask register. That's it, that's the whole job. Lowkey simple, highkey essential. Not me being obsessed with a one-line function but here we are 🌈

⭐ RETURN ⭐

Returns zero on success 🎉 — otherwise you get a negative error number, and that's your cue to go "😭" and check what went wrong.

👑 SEE ALSO 👑

Bestie, buckle up, because this list is long and every single one of these is invited to the group chat. Starting with the kernel file ./include/linux/ntb.h:

Seventy-plus siblings and she's still standing out. Main character energy, no cap 👑

Reminder bestie: she returns zero on success, and a negative error number otherwise. Don't @ me, that's just the facts 💀

That's a wrap! 🌸 This lil page lives in the source directory ./include/linux, is dated October 2026, and goes by ntb_msg_clear_mask(9) — mwah, slay, see you in the next manpage 🫶💖
