get_nulls_value(9)

💖 NAME 💖

okay so welcome to get_nulls_value(9) from the Kernel API Manual, bestie 💅 this one is literally about getting the 'nulls' value of the end of chain — and yes, that's the whole vibe. no cap.

✨ SYNOPSIS ✨

unsigned long get_nulls_value (const struct hlist_nulls_node *ptr );

🎀 ARGUMENTS 🎀

• ptr — end of chain. that's it, that's the argument 🫶

🦋 DESCRIPTION 🦋

okay so the rule here is very much only call this if is_a_nulls(ptr) is true. the original is literally like: Should be called only if is_a_nulls(ptr); — and we are not gonna argue with the kernel docs, periodt. 💀✨
