STRUCT SYNC_TIMELINE(9)

🦋 struct sync_timeline 💖

okay so bestie, this is the struct sync_timeline page from the Kernel API Manual — page struct sync_timeline(9), and it's literally the “sync object” moment. We're keeping every crumb, no skipping, no cap. 💅✨

🌸 NAME 🌸

struct sync_timeline — sync object 🎀

✨ SYNOPSIS ✨

       struct sync_timeline {
           struct kref             kref;
           char name[32];
           u64 context;
           int value;
           struct rb_root          pt_tree;
           struct list_head        pt_list;
           spinlock_t lock;
           struct list_head        sync_timeline_list;
        };

💅 Members 💅

• kref — reference count on fence. That's the whole vibe. 🫶
• name — name of the sync_timeline. Useful for debugging. She's a debug helper, your honor. 🔍
• pt_tree — rbtree of active (unsignaled/errored) sync_pts. Tree structure, but make it active-only. 🌳
• pt_list — list of active (unsignaled/errored) sync_pts. The list version, same active-only energy. 📋
• lock — lock protecting pt_list and value. Do not touch those without the lock, bestie. 🔒
• sync_timeline_list — membership in global sync_timeline_list. She's in the global group chat. 💬

Also, yes, the struct above has u64 context; and int value; — the Members list doesn't give them their own separate blurbs, so I'm not inventing extra lore. 👀✨
