💅 ubifs_ensure_cat — a Kernel API Manual moment

ok so bestie, welcome to the ubifs_ensure_cat(9) page, live from the Kernel API Manual ✨ this one's a little one-function baddie and honestly? she's doing a very specific job and she's slaying it.

🌸 NAME 🌸

ubifs_ensure_cat — ensure LEB properties are categorized.

like, that's literally her whole personality. no cap.

---

🦋 SYNOPSIS 🦋

void ubifs_ensure_cat (struct ubifs_info *c , struct ubifs_lprops
*lprops );

void return, so she doesn't even give you anything back — she just does the thing and dips. main character energy fr 💅

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. iconic. she's the file system herself.
• lprops — LEB properties. the little guy we're checking on 🥺

✨ DESCRIPTION ✨

okay so picture this: a LEB may have fallen off of the bottom of a heap 😭 and ended up as un-categorized even though it has enough space for us now. rude, honestly. the vibes were off.

if that is the case, this function will put the LEB back onto a heap. that's it. that's the whole plot. she rescues the LEB from its un-categorized era and returns it to its rightful heap. no cap, no drama, just vibes restoration 🫶

lowkey love that for the LEB. a come-up arc. we stan 🌈
