ubifs_tnc_start_commit(9)

🌸 NAME 🌸

okay so bestie, welcome to ubifs_tnc_start_commit(9) from the Kernel API Manual 💖 This page is all about start TNC commit, and it's giving deeply specific kernel-internals realness. Periodt.

✨ SYNOPSIS ✨

int ubifs_tnc_start_commit (struct ubifs_info *c , struct ubifs_zbranch
*zroot );

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object, aka the context bestie you pass in 🫶
• zroot — the new index root position is returned here, so this is where the result lands ✨

💅 DESCRIPTION 💅

This function prepares the list of indexing nodes to commit and lays out their positions on flash. Lowkey a whole backstage pass moment for the index 💖

If there is not enough free space, it uses the in-gap commit method. The function returns zero in case of success and a negative error code in case of failure. That's the return vibe check, no cap 😭👑
