gfs2_rgrp_dump(9)

💅 gfs2_rgrp_dump(9) — from the Kernel API Manual, bestie

Okay so picture this: you're deep in the kernel, you've got a resource group in front of you, and you just need to see it. That's literally this function. It prints out an rgrp. That's the whole gig. Iconic, honestly.

---

✨ NAME ✨

gfs2_rgrp_dump — print out an rgrp 🫶

---

🌸 SYNOPSIS 🌸

void gfs2_rgrp_dump (struct seq_file *seq , struct gfs2_rgrpd *rgd ,
       const char *fs_id_buf );

---

🎀 ARGUMENTS 🎀

• seq — the iterator, aka the seq_file you're dumping into. it's giving "where the output goes" energy ✨
• rgd — the rgrp in question 👑 like, the actual resource group we're talking about here
• fs_id_buf — pointer to the file system id (if requested). note the "if requested" — it's conditional, bestie, don't come for me 🙈

🦋 SEE ALSO 🦋

First up, the kernel file itself: ./fs/gfs2/rgrp.c — that's the home base, the main character 💖

Fifty of them. FIFTY. and yes I listed every single one because we don't do half-finished here 💅 go read them, they're literally all in rgrp.c's orbit, iykyk.

ngl there's no exit status, no env vars, no flags to remember here — it's a void function, it returns nothing, it just vibes and prints. sometimes that's enough 🧚

and that's the whole page!! this one came from the Kernel API Manual, dated October 2026, out of ./fs/gfs2 — and it's signed off as gfs2_rgrp_dump(9). slay, periodt, go dump some rgrps 🍓💜
