✨ SYNOPSIS ✨

int layout_in_gaps (struct ubifs_info *c , int cnt );

• c — the UBIFS file-system description object, iconic as always.
• cnt — number of dirty znodes to commit. no cap, that’s the count.

🦋 DESCRIPTION 🦋

okay so this function lays out new index nodes for dirty znodes using the in-the-gaps method of TNC commit. literally what it says on the tin, and the tin is very kernel-core 💅

This function returns 0 on success and a negative error code on failure. the way that success is 0 and failure is a negative error code is very “iykyk” energy 😭✨
