STRUCT MTD_DEV_PARAM(9)

✨ NAME ✨

okay so this is struct mtd_dev_param(9) from the Kernel API Manual, and it's literally the MTD device parameter description data structure. periodt, that's the whole NAME section, bestie.

🌸 SYNOPSIS 🌸

Here's the struct in all its iconic glory — copy it exactly, no editing the vibe:

       struct mtd_dev_param {
           char name[MTD_PARAM_LEN_MAX];
           int ubi_num;
           int vid_hdr_offs;
           int max_beb_per1024;
           int enable_fm;
           int need_resv_pool;
           int wl_threshold;
        };

• name — MTD character device node path, MTD device name, or MTD device number string. iconic string energy.
• ubi_num — UBI number. yes bestie, just the UBI number.
• vid_hdr_offs — VID header offset. offset queen behavior.
• max_beb_per1024 — maximum expected number of bad PEBs per 1024 PEBs. math but make it MTD.
• enable_fm — enable fastmap when value is non-zero. turn it on, slay.
• need_resv_pool — reserve pool->max_size pebs when value is none-zero. reserve pool energy.
• wl_threshold — wear-leveling threshold, 0 means use CONFIG_MTD_UBI_WL_THRESHOLD. zero means default, iykyk.

ngl, none-zero is sending me 💀 but that's the exact wording from the page, so we keep it, fr fr.
