make_ltab_dirty(9)

💖 NAME 💖

okay so this is literally the manual page for make_ltab_dirty(9) from the Kernel API Manual, and its whole job is to make ltab node dirty. That's the name, bestie — no extra lore needed.

🌈 SYNOPSIS 🌈

int make_ltab_dirty (struct ubifs_info *c , int lnum , int offs );

🌸 ARGUMENTS 🌸

• c — UBIFS file-system description object.
• lnum — LEB number where ltab was written.
• offs — offset where ltab was written.

🦋 DESCRIPTION 🦋

This function is used by LPT garbage collection. LPT garbage collection is used only for the "big" LPT model (c->big_lpt == 1). Garbage collection simply involves marking all the nodes in the LEB being garbage-collected as dirty. The dirty nodes are written next commit, after which the LEB is free to be reused.

This function returns 0 on success and a negative error code on failure. Slay.
