okay bestie, welcome to move_up_lpt_heap(9) from the Kernel API Manual ✨ this is the function that moves a new heap entry up as far as possible, and we’re gonna get into it 💅

🌸 NAME 🌸

move_up_lpt_heap — move a new heap entry up as far as possible.

✨ SYNOPSIS ✨

void move_up_lpt_heap (struct ubifs_info *c , struct ubifs_lpt_heap
       *heap , struct ubifs_lprops *lprops , int cat );

🎀 ARGUMENTS 🎀

• c — UBIFS file-system description object.
• heap — LEB category heap.
• lprops — LEB properties to move.
• cat — LEB category.

💫 DESCRIPTION 💫

New entries to a heap are added at the bottom and then moved up until the parent’s value is greater. In the case of LPT’s category heaps, that value is either the amount of free space or the amount of dirty space, depending on the category. That’s the whole vibe check 🔥
