pmd_is_migration_entry(9)

🌸 NAME 🌸

Okay so bestie, this is the manual page for pmd_is_migration_entry(9) — section 9, Kernel API Manual, and it’s lowkey a one-question pop quiz: is this PMD entry encoding a migration entry? That’s the whole assignment. No extra lore, no side quests. 💅✨

✨ SYNOPSIS ✨

Here’s the exact signature, no cap:

bool pmd_is_migration_entry (pmd_t pmd );

🎀 ARGUMENTS 🎀

• pmd — a PMD entry. That’s it. That’s the argument. It’s the thing being checked, and honestly it’s carrying the whole scene. 🫶

💫 RETURN 💫

Returns true if the PMD encodes a migration entry, otherwise false. Two outcomes, both valid, zero ambiguous “maybe” energy. 😌💖
