make_lsave_dirty(9)

💖 NAME 💖

okay bestie, this is the make_lsave_dirty(9) page from the Kernel API Manual, and it's literally about making an lsave node dirty. That's the whole gig. 💅

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

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

🦋 DESCRIPTION 🦋

So this function is used by LPT garbage collection, no cap. And 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. periodt. ✨

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