copy_time_ns(9)

✨ NAME ✨

okay bestie, this is the copy_time_ns(9) Kernel API Manual page, and the whole vibe is: Create timens_for_children from @old_ns. ✨

🌸 SYNOPSIS 🌸

struct time_namespace * copy_time_ns (u64 flags , struct user_namespace
*user_ns , struct time_namespace *old_ns );

🎀 ARGUMENTS 🎀

• flags — the cloning flags, no cap 👑
• user_ns — the user namespace which owns a new namespace 🦋
• old_ns — the namespace to clone, bb 💅

💜 DESCRIPTION 💜

So here’s the tea: if CLONE_NEWTIME is specified in flags, it creates a new timens_for_children; otherwise it adds a refcounter to old_ns. That’s the whole plot. ✨

🔥 RETURN 🔥

It returns the timens_for_children namespace or ERR_PTR. periodt. 💅
