gfs2_free_meta(9)

💖 gfs2_free_meta — Kernel API Manual energy 💖

okay so bestie, welcome to the gfs2_free_meta page, straight out of the Kernel API Manual. yes it's a kernel function, no it's not scary, i promise. it's literally one function and four arguments, we got this 🫶

---

✨ NAME ✨

gfs2_free_meta — free a contiguous run of data block(s) 🎀

like, you're handing blocks back. that's the whole vibe.

---

🌸 SYNOPSIS 🌸

void gfs2_free_meta (struct gfs2_inode *ip , struct gfs2_rgrpd *rgd ,
u64 bstart , u32 blen );

note the void bestie — this one does not return anything back to you. it just does the thing. no cap 💅

---

🦋 ARGUMENTS 🦋

four of them. count 'em. all of them matter, don't skip any 🙈

• ip — the inode these blocks are being freed from. like, whose blocks are these? this one. the inode is the main character here 👑
• rgd — the resource group the blocks are in. this is the neighborhood the blocks live in 🏡
• bstart — first block of a run of contiguous blocks. the starting point. the beginning of the era ✨
• blen — the length of the block run. how many blocks we're talking about, fr fr
