kobject_namespace(9)

okay so welcome to the Kernel API Manual, bestie — today’s main character is kobject_namespace(9), and she’s here to hand you a namespace tag (or a NULL, we’ll get there) 💖✨

💖 NAME 💖

kobject_namespace — return @kobj's namespace tag. that’s the whole vibe, fr fr 💅

🌸 SYNOPSIS 🌸

here’s the signature exactly, no remixing:

const struct ns_common * kobject_namespace (const struct kobject *kobj
);

🎀 ARGUMENTS 🎀

• kobj — the kobject in question, aka the lil guy we’re checking on 🫶

🦋 DESCRIPTION 🦋

okay so here’s the tea ☕: this returns the namespace tag of kobj if its parent has namespace ops enabled and thus kobj should have a namespace tag associated with it. if that condition isn’t happening, it returns NULL otherwise — periodt 💀

lowkey important: the parent having namespace ops enabled is the thing that matters here; otherwise the answer is NULL, no cap.
