STRUCT BINDER_SHRINKER_MDATA(9)

okay bestie, welcome to the Kernel API Manual page for struct binder_shrinker_mdata(9) — the header has that truncated struct binde...rinker_mdata(9) moment, but the NAME section is giving full-name clarity ✨

💖 NAME 💖

so struct binder_shrinker_mdata is literally the binder metadata used to reclaim pages. that’s the whole vibe: binder metadata, page reclaim, iconic little struct behavior 💅

✨ SYNOPSIS ✨

here’s the exact shape, no cap — copy it character for character:

       struct binder_shrinker_mdata {
           struct list_head lru;
           struct binder_alloc *alloc;
           unsigned long page_index;
        };

🎀 Members 🎀

• lru — the LRU entry in binder_freelist. it’s the list-link moment, fr fr.
• alloc — the binder_alloc that owns the page to reclaim. main character pointer energy 🫶
• page_index — the offset in alloc->pages[] into the page to reclaim. yes bestie, it indexes into that array and points at the page situation.
