srcu_notifie...n_unregister(9)

💅 NAME 💅

okay so this is srcu_notifier_chain_unregister — the whole vibe is "remove a notifier from an SRCU notifier chain". like, it's the breakup function for notifiers. we're in the Kernel API Manual, bestie, and this is your girl explaining it 🫶

---

✨ SYNOPSIS ✨

int srcu_notifier_chain_unregister (struct srcu_notifier_head *nh ,
       struct notifier_block *n );

that's it. that's the whole ritual. two args, one int coming back at you 💖

---

🎀 ARGUMENTS 🎀

• nh — pointer to the head of the SRCU notifier chain. yeah, the whole chain's main character. you're handing it over so it knows where the list lives ✨
• n — the entry you want to remove from the notifier chain. this is the one getting yeeted off the list, no cap 🌸

---

🌈 DESCRIPTION 🌈

so what does it actually do? it removes a notifier from an SRCU notifier chain. literally that. the notifier is gone, the chain is shorter, everyone moves on 💅

⚠️ important caveat, bestie, do NOT skip this one: it must be called from process context. like, that's not a suggestion, that's the rule. sleeping context only. periodt 😭

and the return value? if everything goes gorge, it returns zero on success. if it doesn't work out — for example the thing isn't even in there — you get -ENOENT on failure. it's giving "she's not on the list, babe" 💀
