hlist_add_before(9)

💖 NAME 💖

okay so bestie, hlist_add_before(9) is the kernel API manual page for hlist_add_before — it adds a new entry before the one specified. That's literally the whole vibe: new entry, but make it go before the node you point at. ✨

✨ SYNOPSIS ✨

the signature is giving very specific, no cap:

void hlist_add_before (struct hlist_node *n , struct hlist_node *next );

🎀 ARGUMENTS 🎀

two arguments, zero drama — except the very real next must be non-NULL rule 👀

• n — the new entry to be added, the fresh little node stepping into the list 💅
• next — the hlist node to add it before, and this one must be non-NULL, periodt
