STRUCT KSZ_COUNTER_INFO(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this page is all about struct ksz_counter_info, which is literally the OS dependent counter information data structure 💅. that's it, that's the whole vibe. it's the lil struct that keeps track of counter-reading business in an OS-dependent way, and we're gonna walk through every single member together, no cap 🫶

---

🌸 SYNOPSIS 🌸

struct ksz_counter_info {
    wait_queue_head_t counter;
    unsigned long time;
    int read;
 };

she's small, she's iconic, she has exactly three members 👑 ngl sometimes the tiny structs are the ones with the most main character energy 🦋

---

🎀 Members 🎀

• counter — the wait queue that gets woken up after the counters are read 😴➡️✨ like, it's literally in the name, bestie. wakeup happens post-read, that's the whole point.
• time — the next time in jiffies to read the counter ⏰ (yes, jiffies, the kernel's fave unit of time, iykyk). it's when the next counter read is scheduled to go down.
• read — an indication of whether the counters were read in full or not 👀🔍 so like, did we get the whole thing or nah? this field is the receipts.

💀 reminder bestie: this is a man page, not a tutorial — the struct is the star, and the SEE ALSO list is the extended universe. go read them if you're curious, but don't come for me if you get lost in the ksz lore 😭
