inode_init_always_gfp(9)

💅 inode_init_always_gfp(9) — the Kernel API Manual, but make it make sense 🎀

okay so bestie, welcome to inode_init_always_gfp 💖 this is from the Kernel API Manual (yes, the (9) section, we're being fancy today ✨), and it's literally the glow-up routine every inode has to go through. sit down, grab a strawberry drink 🍓, let's get into it.

---

🌸 NAME 🌸

inode_init_always_gfp — the vibes-level task of performing inode structure initialisation. that's it, that's the job 🫶

---

✨ SYNOPSIS ✨

int inode_init_always_gfp (struct super_block *sb , struct inode *inode
, gfp_t gfp );

three args, one int coming back at you. no cap, that's the whole signature 👑

---

🦋 ARGUMENTS 🦋

• sb — the superblock that this inode belongs to. its home base, its main character context 🏠
• inode — the actual inode you're initialising. this is the one getting the makeover 💅
• gfp — the allocation flags. this is what we hand over if extra allocations are needed 🌈

---

💜 DESCRIPTION 💜

so these are the initialisations that have to happen on every single inode allocation, because the fields do not get initialised by slab allocation. like, slab allocation is not doing that for you, bestie, it simply isn't 😭. and if there are additional allocations required, gfp is what gets used — that's why it's right there in the argument list, iykyk 🔥
