STRUCT TTM_OBJECT_FILE(9)

💅 struct ttm_object_file(9) — Kernel API Manual ✨

okay so bestie, welcome to the struct ttm_object_file(9) page — manual-name folded in, vibes immaculate, facts untouched 🫶

🌸 NAME 🌸

struct ttm_object_file — the name line is literally just the struct name; the description field is empty in the original, so no invented lore here 🙈

✨ SYNOPSIS ✨

Here’s the struct exactly as it appears — no edits, no “fixing” the spacing, periodt:

       struct ttm_object_file {
           struct ttm_object_device *tdev;
           spinlock_t lock;
           struct list_head ref_list;
           unsigned long ref_hash[1 << (( VMW_TTM_OBJECT_REF_HT_ORDER) - 1)];
           struct kref refcount;
        };

🎀 Members 🎀

• tdev — pointer to the ttm_object_device. literally its whole job 💖
• lock — the lock that protects the ref_list list and the ref_hash hash tables. bodyguard behavior, no cap 🔒
• ref_list — list of ttm_ref_objects to be destroyed at file release. cleanup crew energy 🧹
• ref_hash — hash tables of ref objects, one per ttm_ref_type, for fast lookup of ref objects given a base object. speed-dating but for refs ⚡
• refcount — reference/usage count. keeping tally, slay 📊
