💅 NAME 💅

okay so bestie, this whole page is about d_unhashed — the little helper that answers “is dentry hashed?” — and it’s from the Kernel API Manual, aka d_unhashed(9). It’s giving “small function, very specific job” energy, and honestly? We respect it. 🎀

🎀 ARGUMENTS 🎀

• dentry — the entry you’re checking, bestie. This is the thing getting the vibe check. 🫶

✨ DESCRIPTION ✨

okay so real talk: d_unhashed() returns true if the dentry you passed in is not currently hashed. That’s it. That’s the function. If it’s not currently hashed, you get true — no cap, that’s the whole read. 💖
