💅 dent_key_init_flash(9) — like, the whole manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual ✨ this one's about dent_key_init_flash, and it is exactly what it sounds like: you're setting up a directory-entry key so it lives happily on flash. short page, but we're gonna give it the energy it deserves 🎀

✨ NAME ✨

dent_key_init_flash — initialize on-flash directory entry key.

like, that's it. that's the whole job. she initializes the on-flash directory entry key and she does it flawlessly 💅

🌸 SYNOPSIS 🌸

void dent_key_init_flash (const struct ubifs_info *c , void *k , ino_t
inum , const struct fscrypt_name *nm );

void return, no cap — she doesn't hand anything back, she just does the thing and dips 🦋

🦋 ARGUMENTS 🦋

four of them, all iconic, all necessary:

  • c — the UBIFS file-system description object. your whole context, your main character, the file system herself 👑
  • k — the key you're initializing. yes this is the one getting the makeover ✨
  • inum — the parent inode number. it's giving "who's your mom" energy, but make it filesystem 🌸
  • nm — the direntry name and length. the name, the length, the whole package 🎀

🔥 SEE ALSO 🔥

okay so the source of truth here is the kernel file ./fs/ubifs/key.h, and she has so many friends. like a whole group chat. the entire key squad, fr fr:

that's thirty-three besties. thirty-three. she's popular 💖 iykyk

ngl bestie, read the whole key.h family before you go poking at keys — they're all lowkey interconnected and you don't wanna be the one who skipped the lore 😭

and that's the page!! ty for coming to my ted talk 🫶

this gem lives over in ./fs/ubifs, and the version notes say October 2026 — so yeah, mark your calendar, she's dated, she's official, she's dent_key_init_flash(9) 💜⭐
