hash_for_eac..._rcu_notrace(9)

💖 hash_for_eac..._rcu_notrace(9) 💖

okay so bestie, welcome to the Kernel API Manual page for hash_for_each_possible_rcu_notrace 🫶. This one is literally here to iterate over all possible objects hashing to the same bucket in an rcu enabled hashtable in an rcu enabled hashtable. yes, the “in an rcu enabled hashtable” bit is in there twice — we keep the facts, even the quirky repeats 💅✨.

✨ SYNOPSIS ✨

code is sacred, so here is the signature exactly as it is:

hash_for_each_possible_rcu_notrace (name , obj , member , key );

🎀 ARGUMENTS 🎀

• name — the hashtable to iterate. that’s the whole vibe: it’s the table you’re walking through 🚶‍♀️💨
• obj — the type * to use as a loop cursor for each entry. yes, the type * matters, bestie — it’s giving pointer energy 💅
• member — the name of the hlist_node within the struct 🎯
• key — the key of the objects to iterate over 🔑

🦋 DESCRIPTION 🦋

This is the same as hash_for_each_possible_rcu except that it does not do any RCU debugging or tracing. that’s the entire difference, no cap 😌.

it literally does not do any RCU debugging or tracing — zero, none, don’t expect extra safety tea from this one 🫖🙈.
