💖 gfs2_rgrp_brelse 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — yes we're in kernel land today, hold my iced coffee 🧊✨

This is the page for gfs2_rgrp_brelse and honestly? She's a short one. A little two-second read, a little palate cleanser, and then we're back to the sixty-function deep lore. Enjoy it while it lasts 🎀

🦋 NAME 🦋

gfs2_rgrp_brelse — the one that goes "okay we're done here" and releases the RG bitmaps that were read in with gfs2_rgrp_bh_get(). That's the whole personality. Cleanup queen behavior, no cap 💅

---

✨ SYNOPSIS ✨

void gfs2_rgrp_brelse (struct gfs2_rgrpd *rgd );

like, that's it. that's the function. void in, void out, vibes immaculate 🌸

🌈 ARGUMENTS 🌈

• rgd — the resource group 👑 (yes, the resource group, the RG in question, the main character of this particular call)

---

🫶 SEE ALSO 🫶

okay so this is the part where the manpage says "here's literally everyone else in ./fs/gfs2/rgrp.c" and then just... lists them all. and honestly? respect. it's giving family reunion. it's giving group chat with fifty people in it. not me knowing every single one of them 💀

💡 friendly reminder bestie: this page is literally four short sections long — if you're looking for the long lore, that SEE ALSO list is your TBR pile and it is not getting shorter 😭

and that's the whole page, bestie, we ate and left no crumbs 🍓 the fine print says this one lives in ./fs/gfs2, stamped October 2026, and the manual is gfs2_rgrp_brelse(9) — mwah, go read the other fifty 💜✨🧚
