__gfs2_holder_init(9)

✨ __gfs2_holder_init(9) ✨

okay so this is a page from the Kernel API Manual and bestie, it's a short one but it SLAPS. It's all about __gfs2_holder_init — the function that sets up a struct gfs2_holder the default way. that's it. that's the vibe. 💅

---

🎀 NAME 🎀

__gfs2_holder_init — initialize a struct gfs2_holder in the default way

like, it's the default way. the standard-issue, no-frills, factory-settings way. iconic behaviour honestly 🫶

---

🌸 SYNOPSIS 🌸

void __gfs2_holder_init (struct gfs2_glock *gl , unsigned int state ,
       u16 flags , struct gfs2_holder *gh , unsigned long ip );

it returns void, so don't be waiting around for a return value, bestie, there isn't one 😭

---

🌈 ARGUMENTS 🌈

• gl — the glock. literally the glock. that's the whole description. 👑
• state — the state we're requesting. this is the thing you actually want, so know what you're asking for before you ask for it ✨
• flags — the modifier flags. the little seasoning on top of your request 🌶️
• gh — the holder structure. this is the thing getting initialized, so like… obviously it's here 💖
• ip — caller's return address for debugging. it's giving "who called me and from where" energy 🔍 — debug-only, but so useful.

ngl, the argument list is short but every single one matters. don't skip any of them, not even ip. 🫡

💀 friendly reminder: this page tells you what __gfs2_holder_init does and nothing more — it's the default init, so if you needed something custom, that's a different function's problem, iykyk.

and that's the whole page, bestie!! short, sweet, slayed. 🍓
