gfs2_struct2blk(9)

💖 gfs2_struct2blk(9) 💖

okay so welcome to the Kernel API Manual corner, bestie — this is the page for gfs2_struct2blk(9), and she is here to do exactly one little compute-stuff job with main character energy. ✨

---

✨ NAME ✨

gfs2_struct2blk — compute stuff 🫶

---

🌸 SYNOPSIS 🌸

unsigned int gfs2_struct2blk (struct gfs2_sbd *sdp , unsigned int
nstruct );

---

🎀 ARGUMENTS 🎀

• sdp — the filesystem. literally the filesystem in question, no cap 💅
• nstruct — the number of structures. yes bestie, that count 🍓

---

🦋 DESCRIPTION 🦋

Okay so this one computes the number of log descriptor blocks needed to hold a certain number of structures of a certain size. That's the whole assignment. It's giving “compute stuff” and honestly? iconic. ✨

No extra drama, no side quests — just the block math for those structures. 💖

---

👑 RETURN 👑

It returns the number of blocks needed — and the minimum is always 1. So yeah, the floor is literally one block, periodt. 💅✨
