napi_get_defer_hard_irqs(9)

💅 napi_get_defer_hard_irqs — like, the kernel-API manual page, bestie ✨

okay so this is napi_get_defer_hard_irqs(9), and yes that "(9)" means it lives in the kernel API manual section — very "I'm not a regular function, I'm a kernel function" energy 👑

---

🌸 NAME 🌸

napi_get_defer_hard_irqs — bestie, this literally gets the NAPI's defer_hard_irqs. that's the whole job. iconic, honestly 🫶

---

✨ SYNOPSIS ✨

u32 napi_get_defer_hard_irqs (const struct napi_struct *n );

like, you hand it a NAPI and it hands you back a u32. match made in heaven 💖

---

🎀 ARGUMENTS 🎀

• n — the napi struct you wanna pull the defer_hard_irqs field from. that's it, that's the argument. she's lowkey the whole point 🦋

---

⭐ RETURN ⭐

it returns the per-NAPI value of the defar_hard_irqs field. and yes bestie, the manpage literally spells it defar_hard_irqs — not me, not my fault, I'm not gonna "fix" it, I'm just the messenger 🙈 (iykyk, typos are forever 💀)

the kernel file ./net/core/dev.h says hi 👋 and also these absolute legends:

• napi_set_defer_hard_irqs(9)
• netdev_set_defer_hard_irqs(9)
• napi_get_gro_flush_timeout(9)
• napi_set_gro_flush_timeout(9)
• netdev_set_gro_flush_timeout(9)

go read those too, they're all in their get/set era and it's giving "complete collection" 🧚💜

no cap — if you only remember one thing: getter in, getter out, per-NAPI value returned. slay 💅
