📦 version 7.3.1, in nixpkgs unstable

💅 rht_for_each_entry(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this is a kernel page, section 9, and it's literally all about looping over a hash chain like a boss 🎀

✨ NAME ✨

rht_for_each_entry — iterate over hash chain of given type 🦋

literally just vibes through a chain of entries of whatever type you want, no cap 💖

✨ SYNOPSIS ✨

rht_for_each_entry (tpos , pos , tbl , hash , member );

periodt. that's the whole signature, copy it exactly, don't be cute with it 💅

✨ ARGUMENTS ✨

  • tpos — the type * to use as a loop cursor 🫶 she's the main character of your loop, the pointer that holds whatever struct type you're iterating as
  • pos — the struct rhash_head to use as a loop cursor 🌸 the lowkey structural one that actually walks the chain
  • tbl — the struct bucket_table 🪣 yeah the bucket table, that's her, that's the whole table you're digging through
  • hash — the hash value / bucket index 🔥 which bucket you're in, iykyk
  • member — name of the struct rhash_head within the hashable struct 💖 like the field name inside your struct that's the rhash_head, so the macro knows how to get from one to the other
