STRUCT ASYNC_SCAN_INFO(9)

🦋 struct async_scan_info — bestie briefing 🦋

okay so this is struct async_scan_info(9) from the Kernel API Manual, and it's literally the struct that keeps track of controller & NSIDs to scan. no cap, it's giving “tiny but important” energy. 💅

🌸 NAME 🌸

struct async_scan_info — keeps track of controller & NSIDs to scan.

✨ SYNOPSIS ✨

the whole struct, exactly as written, bestie:

       struct async_scan_info {
           struct nvme_ctrl *ctrl;
           atomic_t next_nsid;
           __le32 *ns_list;
        };

🫶 Members 🫶

• ctrl — Controller on which namespaces are being scanned 👑
• next_nsid — Index of next NSID to scan in ns_list 🔥
• ns_list — Pointer to list of NSIDs to scan 🎀

😭 Note 😭

There is a single async_scan_info structure shared by all instances of nvme_scan_ns_async scanning a given controller, so the atomic operations on next_nsid are critical to ensure each instance scans a unique NSID. fr fr, that atomic bit is the main character. 🫶
