drm_mm_scan_add_block(9)

Okay bestie, welcome to drm_mm_scan_add_block(9) from the Kernel API Manual — it’s giving “tiny but important kernel helper” energy, and we’re gonna get into it. 🎀

💖 NAME

drm_mm_scan_add_block — add a node to the scan list

✨ SYNOPSIS

bool drm_mm_scan_add_block (struct drm_mm_scan *scan , struct
       drm_mm_node *node );

🌸 ARGUMENTS

• scan — the active drm_mm scanner. Like, the scanner that is currently scanning. Main character scanner vibes. 💅
• node — drm_mm_node to add. This is the node bestie is adding to the scan list.

🦋 DESCRIPTION

Add a node to the scan list that might be freed to make space for the desired hole. That’s it, that’s the whole plot. The scan list is collecting nodes that might get freed so the desired hole can happen, and you’re adding one to it. No cap. ✨

⭐ RETURN

Returns True if a hole has been found, false otherwise.
