STRUCT KVFREE_RCU_BULK_DATA(9)

✨ NAME ✨

struct kvfree_rcu_bulk_data — bestie, it's literally just one single block whose whole job is to hold kvfree_rcu() pointers 💅 that's it, that's the vibe

🎀 SYNOPSIS 🎀

struct kvfree_rcu_bulk_data {
    struct list_head list;
    struct rcu_gp_seq gp_snap;
    unsigned long nr_records;
    void *records[];
};

okay so this is from the Kernel API Manual (section 9, kernel API girlies rise 🫶) and yes the last member is a flexible array, she's iconic like that ✨

💖 MEMBERS 💖

• list — the list node, no cap 📋 every single one of these blocks is linked between each other, so they're all holding hands in a big linked-list chain 🫶
• gp_snap — a snapshot of the RCU state for the objects that got placed into this bulk 🌸 it's giving "receipts of the moment they arrived"
• nr_records — the number of active pointers in the array 🔥 like how many spots are actually being used rn
• records — the array itself, holding the kvfree_rcu pointers 💜 the main character of the whole struct ngl

periodt 💀 that's every single one of them, don't come for me about the list length, I copied it exactly fr fr

okay bestie that's the whole page 🌈 this lil drop came from ./mm, dated October 2026, and it's filed under struct kvfree_rcu_bulk_data(9) — slay, go free some pointers responsibly 💅🎀
