maybe_leb_gced(9)

🌸 NAME 🌸

Okay so welcome to maybe_leb_gced(9) from the Kernel API Manual — this is the function that determines if a LEB may have been garbage collected. It’s giving quick vibe check for GC, and honestly? Iconic.

🛰️ SYNOPSIS 🛰️

Copy the signature exactly, bestie:

int maybe_leb_gced (struct ubifs_info *c , int lnum , int gc_seq1 );

💖 ARGUMENTS 💖

• c — UBIFS file-system description object. That’s the context object, periodt.
• lnum — LEB number. The LEB we’re checking on.
• gc_seq1 — garbage collection sequence number. The GC sequence number in question.

🔥 DESCRIPTION 🔥

Here’s the whole plot: this function determines if lnum may have been garbage collected since sequence number gc_seq1.

If it may have been, then 1 is returned. Otherwise, 0 is returned. That’s it, no cap. 💅
