STRUCT MPI3MR_CHANGE_COUNT(9)

💅 struct mpi3mr_change_count(9)

okay so bestie, welcome to the Kernel API Manual ✨ — yes that's the manual name, and yes you're gonna read it, because this one is short and honestly kind of a vibe. It lives in the kernel API docs and it's all about a tiny lil struct that carries a topology change count back from the driver 🦋

---

🌸 NAME 🌸

struct mpi3mr_change_count — the topology change count that the driver hands back to you. That's it, that's the whole thing 💖

---

🎀 SYNOPSIS 🎀

struct mpi3mr_change_count {
    __u16 change_count;
    __u16 rsvd;
 };

look at her. two __u16s. absolutely iconic, no notes 👑

---

✨ Members ✨

• change_count — the topology change count, literally the main character of this struct 🌟
• rsvd — reserved. she's not for you, bestie, she's just holding space 🙈

---

🔥 SEE ALSO 🔥

• Kernel file ./include/uapi/scsi/scsi_bsg_mpi3mr.h — that's where the family lives, go say hi 🫶

and the whole friend group, all structs, all getting their own manpage, all slaying in their own way:

• struct mpi3_driver_info_layout(9)
• struct mpi3mr_bsg_in_adpinfo(9)
• struct mpi3mr_bsg_adp_reset(9)
• struct mpi3mr_device_map_info(9)
• struct mpi3mr_all_tgt_info(9)
• struct mpi3mr_logdata_enable(9)
• struct mpi3mr_bsg_out_pel_enable(9)
• struct mpi3mr_logdata_entry(9)
• struct mpi3mr_bsg_in_log_data(9)
• struct mpi3mr_hdb_entry(9)
• struct mpi3mr_bsg_in_hdb_status(9)
• struct mpi3mr_bsg_out_repost_hdb(9)
• struct mpi3mr_bsg_out_upload_hdb(9)
• struct mpi3mr_bsg_out_refresh_hdb_triggers(9)

• struct mpi3mr_bsg_mptcmd(9)
• struct mpi3mr_bsg_packet(9)

it's giving extended universe, fr fr 💀

lowkey reminder: rsvd is reserved — don't go poking at it and then act surprised, bestie 😭

and that's a wrap, babe 🌈 this little page is filed under ./include/uapi/scsi, dated October 2026, and yes the header says struct mpi3mr_change_count(9) twice because the manpage template is extra like that. periodt. 💅🎀
