🌸 ubifs_return_leb — bestie, it's time to give that LEB back 💅

okay so picture this: this is a Kernel API Manual page for ubifs_return_leb, out of the UBIFS crowd in ./fs/ubifs, and honestly? she's a tiny little helper with one job and she does it flawlessly. 🦋

✨ NAME ✨

ubifs_return_leb — return LEB to lprops. that's it. that's the whole vibe. 🎀

---

💖 SYNOPSIS 💖

int ubifs_return_leb (struct ubifs_info *c , int lnum );

like, look at her. two args, one int coming back at you. lowkey iconic. ✨

---

🫶 ARGUMENTS 🫶

• c — the UBIFS file-system description object. yes bestie, the whole file-system said "hi" 🥰
• lnum — the LEB to return. this is the eraseblock that's packing its bags and heading home 🧚

---

🔥 DESCRIPTION 🔥

so what does she actually do? this helper function cleans the "taken" flag of a logical eraseblock in the lprops. the flag was doing its little "reserved ✋" moment, and she's the one who's like "okay king, you can go now, we're done." 💀

returns zero in case of success and a negative error code in case of failure. so if you get 0, celebrate 🎉, and if you get anything negative, that's your sign to go look at what went wrong. no cap. 😭
