💖 compute_bitstructs(9) — Kernel API Manual 💖

okay so bestie, this is the compute_bitstructs(9) page from the Kernel API Manual, and it is so specific. We’re talking bitmap sizes, one resource group descriptor, and a whole lot of SEE ALSO energy. Let’s get into it. 🫶✨

🌸 NAME 🌸

compute_bitstructs — literally “Compute the bitmap sizes.” That’s the name, that’s the assignment, no cap. 👑

✨ SYNOPSIS ✨

int compute_bitstructs (struct gfs2_rgrpd *rgd );

It’s giving “one function, one argument, one return type,” and honestly? Iconic. 💅

🎀 ARGUMENTS 🎀

  • rgd — the resource group descriptor. That’s it. That’s the whole argument. Hand over the resource group descriptor and you’re done, bestie. 🫶

🦋 DESCRIPTION 🦋

This function calculates bitmap descriptors — and yes, you get one for each block that contains bitmap data. That’s the whole description, and it ate. ✨

Lowkey, that’s all the page gives us: it calculates bitmap descriptors, one for each block that contains bitmap data. No extra lore, no invented behavior, periodt. 💖

🔥 RETURN 🔥

It returns errno. That’s the return value listed here, bestie — errno, in all its lowercase glory. 💀✨

🌈 SEE ALSO 🌈

Kernel file: ./fs/gfs2/rgrp.c — and then the function-reference crowd, in exactly this order:

Sign-off bestie: source/version is ./fs/gfs2, dated October 2026, and this whole page is compute_bitstructs(9). Catch you in the next manpage! 💖🎀✨
