💖 dm_copy_name_and_uuid(9) 💖

okay so welcome to the Kernel API Manual, bestie — section 9, we're in the kernel-adjacent group chat now ✨ This little icon is literally about copying a mapped device's name & uuid into buffers you supply 🫶

✨ NAME ✨

dm_copy_name_and_uuid — copy mapped device name & uuid into supplied buffers 💅

🦋 SYNOPSIS 🦋

int dm_copy_name_and_uuid (struct mapped_device *md , char *name , char *uuid );

🎀 ARGUMENTS 🎀

• md — pointer to mapped_device 👑
• name — buffer (size DM_NAME_LEN) for name 🎀
• uuid — buffer (size DM_UUID_LEN) for uuid or empty string if uuid not defined 🦋

bestie, those buffer sizes are not a vibe check you can skip — DM_NAME_LEN for name, DM_UUID_LEN for uuid, periodt 💀

• Kernel file ./drivers/md/dm-ioctl.c and dm_early_create(9) ⭐
