💅 netlbl_af4list_remove(9) 💅

okay so bestie, welcome to the Kernel API Manual 🎀 — yes we're in the kernel today, and no it's not scary, i promise. this one's a lil function that just... removes an IPv4 address entry. that's the whole vibe. let's get into it ✨

🌸 NAME 🌸

netlbl_af4list_remove — remove an IPv4 address entry 🧹💖

✨ SYNOPSIS ✨

struct netlbl_af4list * netlbl_af4list_remove (__be32 addr , __be32 mask , struct list_head *head );

like, it returns a struct netlbl_af4list *, and it takes three (3) whole arguments. main character function fr fr 👑

🦋 ARGUMENTS 🦋

  • addr — the IP address. literally just the IP address, that's it, that's the whole thing 💫
  • mask — the IP address mask. it's the mask that goes with the address, they're a matching set, a duo, an iconic pair 🫶
  • head — the list head. this is the head of the list bestie, everything happens through her 👑

💜 DESCRIPTION 💜

so the way that this works is: it removes an IP address entry from the list pointed to by head. simple as that, no cap 🌈

it returns the entry on success — yay 🎉 — and NULL on failure 💀. so like, check your return value, always, i'm begging 🙈

⚠️ the caller is responsible for calling the necessary locking functions. this is not a drill bestie, you gotta do the locking yourself, it's your job not hers, periodt 🔥
