STRUCT UFS_STATS(9)

💖 struct ufs_stats(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for struct ufs_stats(9), and she is literally here to keep usage/err statistics. no cap. 🫶

✨ NAME ✨

struct ufs_stats — keeps usage/err statistics. periodt. 💅

🦋 SYNOPSIS 🦋

struct ufs_stats {
    u32 hibern8_exit_cnt;
    u64 last_hibern8_exit_tstamp;
    struct ufs_event_hist event[UFS_EVT_CNT];
 };

that's the whole struct, laid out exactly like that. ✨

🌸 Members 🌸

• hibern8_exit_cnt — counter to keep track of the number of exits, bestie. reset this after link-startup. 🔁
• last_hibern8_exit_tstamp — set the time after the hibern8 exit. clear it after the first successful command completion. ⏰
• event — array with event history. 🗂️
