fixup_free_space(9)

💅 NAME 💅

okay bestie, welcome to the fixup_free_space(9) manual page from the Kernel API Manual — the main character here is fixup_free_space, and its whole vibe is: find & remap all LEBs containing free space. No cap, that's the name description, periodt. 💖

✨ SYNOPSIS ✨

int fixup_free_space (struct ubifs_info *c );

It hands you back an int, because of course it does. 💁‍♀️

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object, typed as struct ubifs_info *. That's the one thing you pass in, bestie. 🫶

🌸 DESCRIPTION 🌸

So here's the tea: fixup_free_space() walks through all LEBs in the filesystem and fixes up those containing free/empty space. That's literally the whole description — no secret side quests, no extra flags, just LEB-by-LEB cleanup energy. ✨
