statfs_slow_fill(9)

💅 statfs_slow_fill(9) 💅

okay so bestie, welcome to the statfs_slow_fill page — that's the kernel API name, and yes it's a mouthful, but stay with me because this one is short and honestly kind of a vibe ✨

---

🌸 NAME 🌸

statfs_slow_fill — fill in the sg for a given RG 🫶

like, that's the whole thing. it fills in the sg, for an RG. iconic, brief, no notes 💅

---

✨ SYNOPSIS ✨

int statfs_slow_fill (struct gfs2_rgrpd *rgd , struct
gfs2_statfs_change_host *sc );

look at that signature, it's giving function. it returns an int, it takes two pointers, and it is literally right there in ./fs/gfs2/super.c (iykyk, more on that below) 🌈

---

🎀 ARGUMENTS 🎀

• rgd — the RG. that's it, that's the description. it's the RG bestie, we're not gonna over-explain it 💀
• sc — the sc structure. yes, the sc structure. the structure named sc. we love a self-explanatory abbreviation 🍓

---

💖 RETURN 💖

• 0 — success! slay! everything went off without a hitch 👑
• -ESTALE — happens if the LVB is invalid. so if you get this one back, it's a stale-vibe situation, no cap 😭

lowkey reminder: statfs_slow_fill is not one of the gfs2_-prefixed besties, so don't go looking for gfs2_statfs_slow_fill(9) — that's not a thing, don't do that to yourself 🙈
