pmd_is_valid_softleaf(9)

💅 NAME 💅

okay bestie, welcome to pmd_is_valid_softleaf(9) from the Kernel API Manual — the little function that answers: is this PMD entry a valid softleaf entry? 👀✨

🌸 SYNOPSIS 🌸

bool pmd_is_valid_softleaf (pmd_t pmd );

🎀 ARGUMENTS 🎀

• pmd — a PMD entry. That's the thing getting the vibe check. 💅

🦋 DESCRIPTION 🦋

okay so here's the tea, fr fr: PMD leaf entries are valid only if they are device private or migration entries. This function asserts that a PMD leaf entry is valid in this respect. No cap. 🫶

It's giving strict little validity check energy — it's literally asserting that exact rule, nothing extra. 🌈

⭐ RETURN ⭐

• true — if the PMD entry is a valid leaf entry 🎉
• false — otherwise 💀
