ubifs_find_dirty_idx_leb(9)

📦 version 7.3.1, in nixpkgs unstable

✨ ubifs_find_dirty_idx_leb — the kernel API manual, but make it make sense ✨

okay so bestie, welcome to the group chat 💅 this is the page for ubifs_find_dirty_idx_leb(9) from the Kernel API Manual, and honestly? it's giving "one very specific little helper function that does exactly one thing and we respect it for that" 🎀

🌸 NAME 🌸

ubifs_find_dirty_idx_leb — literally just trying to find the dirtiest index LEB as of the last commit 🧚 no cap, that's the whole job

🦋 SYNOPSIS 🦋

int ubifs_find_dirty_idx_leb (struct ubifs_info *c );

one function, one argument, one int coming back at you ✨ iconic, minimal, no notes

💖 ARGUMENTS 💖

  • c — the UBIFS file-system description object 🗂️ like, the whole file system's little info bundle. that's the vibe.

👑 DESCRIPTION 👑

so here's the tea ☕️ this function attempts to find an untaken index LEB that has the most free and dirty space — and the key part, bestie, is that it has to be usable without overwriting index nodes that were in the last index committed 🫶

read that again because it's lowkey the whole point 💀 it's not just "find a dirty one", it's "find a dirty one that's safe", and those are very different energy. untaken ✅ most free and dirty space ✅ doesn't clobber the last-committed index nodes ✅

that's it. that's the function. slay. 🔥

💜 SEE ALSO 💜

this next part is a whole friend group, so let's do a roll call 📣 all of these are from the Kernel file ./fs/ubifs/find.c:

look at that squad 😭 every single one accounted for, nobody left on read 💅

ngl, if you're reading this page you're probably already deep in UBIFS index GC internals — and honestly? main character energy. go off. 🌈

and that's a wrap, bestie 🎀 this page lives at ./fs/ubifs in the Kernel API Manual, dated October 2026 — so like, mark your calendar or whatever, because that's the version/date stamp and we're mentioning it in the sign-off like the little footnote it is 🫶✨ bye, love you, go read find.c 💖
