disk_unblock_events(9)

💅 disk_unblock_events — like, the Kernel API Manual page, bestie 🎀

okay so picture this: you're deep in the kernel, it's giving kernel API manual energy, and you need to stop blocking disk event checking. welcome to disk_unblock_events(9). this is the glow-up page for it. ✨

---

😌 NAME

disk_unblock_events — unblock disk event checking 🦋

like literally just... unblocking. the un-blocking of the disk events. that's the whole vibe.

---

✨ SYNOPSIS

void disk_unblock_events (struct gendisk *disk );

no cap, that's it. one function, one argument, returns void (so like, it doesn't hand you anything back — it just does the thing). 💅

---

🌸 ARGUMENTS

• disk — the disk you wanna unblock events for. yeah. that disk. the struct gendisk * one. 🫶

---

💖 DESCRIPTION

okay so this is literally the undo button for disk_block_events. you blocked 'em, now you're unblocking 'em. character development fr fr. 😭

when the block count reaches zero — like, zero zero, the countdown hits the bottom — it starts events polling if that's configured. so basically, once nobody's blocking anymore, polling can wake back up and go do its little polling thing. iconic behaviour, honestly. 🌈

---

🔥 CONTEXT

"Don't care." — the manpage, literally. 💀

it's safe to call from irq context. yes bestie, even there. no stress, no fuss, no "are we allowed to be here" energy. it's giving unbothered. 👑
