💅 __erase_worker — the Kernel API Manual moment, bestie

okay so we're literally in the kernel API manual rn and the star of the show is __erase_worker(9) — the physical eraseblock erase worker function. yes that's a mouthful, no i will not be shortening it, it's iconic. 🎀

✨ NAME ✨

__erase_worker — physical eraseblock erase worker function. that's it. that's the whole vibe. she erases physical eraseblocks and she does it well. 👑

🌸 SYNOPSIS 🌸

int __erase_worker (struct ubi_device *ubi , struct ubi_work *wl_wrk );

like, she takes two things and gives you back an int. lowkey simple, highkey important. 💅

🦋 ARGUMENTS 🦋

  • ubi — the UBI device description object. this is the whole device's little ID card, her whole personality. 🪪
  • wl_wrk — the work object. the actual task she's about to do, the main character of this specific errand. ✨

💖 DESCRIPTION 💖

okay so picture this: __erase_worker erases a physical eraseblock. and then — because she's thorough, because she's that girl — she also performs torture testing if needed. torture testing!! not me being dramatic, that's literally what the manpage says. 🔥

she also takes care about marking the physical eraseblock bad if needed. so if the block is giving nothing but red flags, she flags it. respectfully. 🚩

return value tea: returns zero in case of success and a negative error code in case of failure. zero = slay, negative = 😭. fr fr, no in-between.

🌈 SEE ALSO 🌈

the whole group chat, and yes we're tagging everyone:

and where does she live? in the kernel file ./drivers/mtd/ubi/wl.c. go visit her, she'd love that. 🫶

okay that's the page!! shoutout to ./drivers/mtd/ubi for being the source, October 2026 for the date, and to you for reading all the way down here — ily, go erase something (safely). 💜🧚‍♀️⭐
