del_mtd_device(9)

✨ del_mtd_device 💅

okay so bestie, this is a page straight out of the Kernel API Manual (that's the manual name btw, cute right?) and it's all about yeeting an MTD device out of the kernel's little friend group. it's giving "removing someone from the group chat" energy, but make it kernel. 🌸

---

🎀 SYNOPSIS 🎀

int del_mtd_device (struct mtd_info *mtd );

that's it. one function, one arg, one int coming back at you. no cap. ✨

---

🦋 ARGUMENTS 🦋

• mtd — pointer to the MTD device info structure. like, the actual struct of the device you're about to un-alive from the registry. 🫶

---

💖 DESCRIPTION 💖

so what does it actually do? two things, and honestly? iconic behaviour:

1. it removes the device from the list of MTD devices present in the system — like, it's off the roster now.
2. it notifies each currently active MTD 'user' of its departure — yes bestie, everybody currently using it gets the heads-up. it's a whole goodbye tour. 😭

now for the return value, listen up:

• returns zero on success (slay 💅)
• returns 1 on failure — and currently that failure happens if the requested device does not appear to be present in the list. so like, you tried to remove something that was never there. awk. 💀

fr fr, that's the whole description. short, sweet, does exactly what it says.

like I said. a lot. but now you know where to look. iykyk 🧚

friendly reminder: if the device isn't in the list, you get 1 back, not zero. don't be out here assuming success. 🙈
