dbg_check_idx_size(9)

💅 dbg_check_idx_size — check index size ✨

Okay bestie, so this one is from the Kernel API Manual (section 9, kernel API vibes only 🫶) and it's literally just dbg_check_idx_size doing a little vibe check on the UBIFS index. Let's get into it 🌸

---

✨ SYNOPSIS ✨

int dbg_check_idx_size (struct ubifs_info *c , long long idx_size );

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object 💖 like, this is the whole filesystem's little passport, ok?
• idx_size — the size you want to check 🔍 the number going under the microscope, no cap

---

🌸 DESCRIPTION 🌸

So what this function does is it walks the UBIFS index — literally strolls through it, main character energy — calculates its size, and then checks that the size it just calculated is equivalent to idx_size. That's it. That's the whole plot 🦋

Returns zero in case of success ✨ and a negative error code in case of failure 💀 (so like, zero = slay, negative = not slay).
