__gfs2_free_blocks(9)

✨ __gfs2_free_blocks ✨

okay so bestie, welcome to the kernel API manual page for __gfs2_free_blocks(9) — yes the double underscore is part of the name, she's fancy like that 💅

---

🎀 NAME 🎀

__gfs2_free_blocks — free a contiguous run of block(s). that's it, that's the whole vibe. we're giving blocks back to the filesystem, no cap 🫶

---

🌸 SYNOPSIS 🌸

void __gfs2_free_blocks (struct gfs2_inode *ip , struct gfs2_rgrpd *rgd
, u64 bstart , u32 blen , int meta );

lowkey a five-argument situation, so let's meet the cast 🎬

---

🦋 ARGUMENTS 🦋

• ip — the inode these blocks are being freed from. like, who's the one letting go of the blocks? it's her. she's the main character of this free-ing 💖
• rgd — the resource group the blocks are in. think of it as the neighborhood where the blocks live 🏡
• bstart — first block of a run of contiguous blocks. the starting point, the origin story, the opener if you will ✨
• blen — the length of the block run. how many blocks we're freeing in this stretch, fr fr
• meta — 1 if the blocks represent metadata. literal numeric flag energy: 1 means yep, metadata; that's the whole deal 🧚
