STRUCT MIGRATE_RANGE_LOC(9)

💅 struct migrate_range_loc(9) 💅

okay bestie, welcome to the Kernel API Manual — we're talking about struct migrate_range_loc(9) and it is literally giving cursor energy in the best way. Not a mouse cursor. A struct cursor. Iconic. 🫶

✨ NAME ✨

struct migrate_range_loc — the cursor into the loop over migrate_pfns for migrating to device. That's the whole vibe, no cap. 💅

🌸 SYNOPSIS 🌸

       struct migrate_range_loc {
           unsigned long start;
           struct device *device;
           struct drm_pagemap *dpagemap;
           const struct drm_pagemap_devmem_ops *ops;
        };

🎀 Members 🎀

• start — the current loop index. Your little loop-position bestie. ✨
• device — the migrating device. 💅
• dpagemap — pointer to struct drm_pagemap used by the migrating device. 🫶
• ops — the copy ops to be used for the migrating device. 🎀
