match_dev_by_uuid(9)

✨ NAME ✨

okay so bestie, quick intro: match_dev_by_uuid — it's literally the callback for finding a partition using its uuid. that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

int match_dev_by_uuid (struct device *dev , const void *data );

🎀 ARGUMENTS 🎀

• dev — the device that the caller passes in. it just shows up and gets checked, no cap 🫶
• data — an opaque pointer to the desired struct uuidcmp you wanna match against. yes bestie, opaque, don't peek inside it, that's the whole point 🙈

💖 DESCRIPTION 💖

so the way this works is: it returns 1 if the device matches, and 0 otherwise. that's it. that's the function. binary queen behavior 👑✨

🦋 SEE ALSO 🦋

• Kernel file ./block/early-lookup.c
• devt_from_partuuid(9)
• match_dev_by_label(9)

ngl, if you're poking around in the block layer early lookup stuff, go read those two, they're like... the sibling functions fr fr 💜

🌸 mwah, that's a wrap! this little gem lives in ./block and the version/date stamp on it is October 2026 — iconic of it, honestly. bye bestie, go match some uuids 💖🎀🦋
