💖 valuable(9): the Kernel API Manual cutie 💖

okay so bestie, welcome to valuable(9) from the Kernel API Manual. This is the tiny little function that answers one extremely specific question: are these LEB properties, like, valuable enough to be added to the LEB properties tree in memory? It’s giving “vibe check but for kernel data structures.” 💅

✨ NAME ✨

valuable — determine whether LEB properties are valuable. periodt.

📜 SYNOPSIS 📜

int valuable (struct ubifs_info *c , const struct ubifs_lprops *lprops
);

🧸 ARGUMENTS 🧸

• c — the UBIFS file-system description object. literally that.
• lprops — LEB properties. yup, the LEB properties right there.

🌸 DESCRIPTION 🌸

So here’s the tea: this function returns 1 if the LEB properties should be added to the LEB properties tree in memory. Otherwise 0 is returned. That’s the whole main character moment — no extra lore, no side quests. 🫶
