d_same_name(9)

💅 d_same_name(9) — NAME ✨

okay bestie, this is the d_same_name(9) page from the Kernel API Manual, and it's giving "tiny dentry name comparison function that knows exactly what it is." The name? d_same_name — compare dentry name with case-exact name. Periodt.

🎀 SYNOPSIS 🎀

Here's the signature, copy it exactly because we do not freestyle C types in this house:

bool d_same_name (const struct dentry *dentry , const struct dentry
       *parent , const struct qstr *name );

🌸 ARGUMENTS 🌸

• dentry — the negative dentry that was passed to the parent's lookup func. That's the dentry being checked, bestie. 💅
• parent — parent dentry. Yes, the parent dentry. The one doing the parenting.
• name — the case-exact name to be associated with the returned dentry. Case-exact is the vibe: exact case, no lowercase chaos.

🔥 RETURN 🔥

She returns true if names are same, or false. That's it. The whole return section is a vibe check. 💀
