xa_init_flags(9)

💅 NAME 💅

Okay bestie, welcome to xa_init_flags(9) from the Kernel API Manual. This one is literally “Initialise an empty XArray with flags.” 🫶

---

✨ SYNOPSIS ✨

void xa_init_flags (struct xarray *xa , gfp_t flags );

---

🎀 ARGUMENTS 🎀

• xa — the XArray. That’s the baby you’re setting up. 💖
• flags — the XA_FLAG values. Yes, flags. Plural. Slay. ✨

---

🦋 DESCRIPTION 🦋

So here’s the tea: if you need to initialise an XArray with special flags — eg you need to take the lock from interrupt context — use this function instead of xa_init. It’s giving “special-case setup” and it’s iconic for exactly that. 💅

---

🌸 CONTEXT 🌸

Any context. No cap, any context. 🫶
