💅 onenand_mlc_read_ops_nolock(9) 💅

okay so bestie, we're in the Kernel API Manual today and the star of the show is onenand_mlc_read_ops_nolock(9). yes that's a whole mouthful, no i will not be shortening it, it's iconic as is 🎀

🌸 NAME 🌸

onenand_mlc_read_ops_nolock — literally the MLC OneNAND read for main and/or out-of-band. that's the whole vibe ✨

🦋 SYNOPSIS 🦋

int onenand_mlc_read_ops_nolock (struct mtd_info *mtd , loff_t from ,
       struct mtd_oob_ops *ops );

like, look at her go 💅

🎀 ARGUMENTS 🎀

  • mtd — the MTD device structure. the main character of the data structure world, we love her 🫶
  • from — the offset you're reading from. where the tea starts, basically ⭐
  • ops — the oob operation description structure. it's giving instructions, it's giving structure, it's giving oob 🍓

💖 DESCRIPTION 💖

okay so here's the lore: MLC OneNAND / Flex-OneNAND has a 4KB page size and a 4KB dataram. and because of that? read-while-load is not present. nope. not a thing here. absent. missing. she simply does not exist 😭

so like... don't go looking for read-while-load on these, bestie, it's not coming to the group chat 💀

🔥 SEE ALSO 🔥

the whole friend group, fr fr — every single one of them:

also the kernel file itself lives at ./drivers/mtd/nand/onenand/onenand_base.c — go say hi, she's the source of truth 🧚

ngl, that SEE ALSO list is a whole squad. iykyk 💜

and that's the whole page, bestie! brought to you by the Kernel API Manual, from ./drivers/mtd/nand/onenand, dated October 2026, and yes it's still called onenand_mlc_read_ops_nolock(9) — slay, periodt 👑💖
