💖 lsm_inode_alloc — Kernel API Manual ✨

okay so bestie, welcome to lsm_inode_alloc(9), straight out of the Kernel API Manual 💅 this one is short and sweet but she is load-bearing, so pay attention.

🌸 NAME 🌸

lsm_inode_alloc — allocate a composite inode blob 🎀

like yes, that's the whole name, no notes, she said what she said.

✨ SYNOPSIS ✨

int lsm_inode_alloc (struct inode *inode , gfp_t gfp );

look at her. iconic signature. no cap. 🦋

🫶 ARGUMENTS 🫶

  • inode — the inode that needs a blob. literally the main character here, she's the one getting the glow-up ✨
  • gfp — allocation flags. the vibe parameters, iykyk 💫

🌈 DESCRIPTION 🌈

So what does she do? She allocates the inode blob for all the modules. that's it. that's the whole job. she's out here making sure every module gets their little spot 🥹

Returns 0, or -ENOMEM if memory can't be allocated. so like, if the memory allocation flops, you get -ENOMEM back and you're gonna have to deal with that 💀 not me ignoring a negative return value, couldn't be me 🙈

fr fr check that return value, bestie. 0 = slay, -ENOMEM = memory said no 💔
