dbg_check_bud_bytes(9)

💅 dbg_check_bud_bytes — like, from the Kernel API Manual, bestie 🎀

Okay so real talk, this is one of those tiny little debug functions that nobody talks about but it's lowkey doing the lord's work. It lives in the UBIFS corner of the kernel, and its whole personality is: "girl, let me double-check that math for you." ✨

---

🌸 NAME 🌸

dbg_check_bud_bytes — makes sure the bud bytes calculation is all right. Like, actually all right. No cap. 💯

---

🦋 SYNOPSIS 🦋

int dbg_check_bud_bytes (struct ubifs_info *c );

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. That's the vibe. That's the whole main character of this function. 🫶

---

✨ DESCRIPTION ✨

So here's the tea: this function goes and makes sure that the amount of flash space used by closed buds is actually correct — and yes, we mean c->bud_bytes, the actual number, not a vibe-based estimate. It's giving quality control. It's giving accountability. 💅

Then it reports back:

• it returns zero in case of success — slay, everything checks out 👑
• it returns -EINVAL in case of failure — 😭 something is wrong and the number is lying to you

Fr fr, that's the whole function. Small but mighty. Don't sleep on it. 🧚
