💖 init_constants_early(9) 💖

okay so welcome to the Kernel API Manual, bestie — this is the page for init_constants_early(9), and it’s all about getting UBIFS constants set up early. 🦋

✨ NAME ✨

init_constants_early — initialize UBIFS constants.

🌸 SYNOPSIS 🌸

int init_constants_early (struct ubifs_info *c );

🎀 ARGUMENTS 🎀

• c — UBIFS file-system description object. literally the main-character struct here 💅

🧚 DESCRIPTION 🧚

So this function initializes UBIFS constants that do not need the superblock to be read. It also checks that the UBI volume satisfies basic UBIFS requirements.

Returns zero in case of success and a negative error code in case of failure. no cap, that’s the whole vibe check ✨
