💫 ubi_sync(9) 💫

okay so bestie, welcome to the ubi_sync(9) page — straight out of the Kernel API Manual, no cap. pull up a chair, we're syncing some buffers 💅

---

✨ NAME ✨

ubi_sync — synchronize UBI device buffers.

like, literally flush the vibes. the buffers' vibes. 🦋

---

🌸 SYNOPSIS 🌸

int ubi_sync (int ubi_num );

that's it. that's the whole call. one int in, one int out, main character energy 🔥

---

🎀 ARGUMENTS 🎀

• ubi_num — the UBI device you wanna synchronize. yes, that one. give it the number of the device you're trying to sync up 💖

---

🧚 DESCRIPTION 🧚

okay so here's the tea ☕ — the underlying MTD device might be caching data, right? like, in hardware, or in software. either way, it's holding onto stuff.

this function makes sure the caches are flushed. that's the whole job. it's giving "clean up your room before guests arrive" energy 🙈

and the return value? iconic behavior:

• returns zero in case of success 🎉
• returns a negative error code in case of failure 😭

that's it, that's the function. no notes. periodt. 💅
