disk_block_events(9)

💖 disk_block_events(9) 💖

okay bestie so this is a page straight out of the Kernel API Manual — like, the kernel's own group chat rules — and today's main character is disk_block_events. yes it's a (9) page, which is kernel-speak for "grown-up developer info, not your cute little user command." slay.

✨ NAME ✨

disk_block_events — block and flush disk event checking, no cap 🛑

✨ SYNOPSIS ✨

void disk_block_events (struct gendisk *disk );

✨ ARGUMENTS ✨

• disk — the disk you wanna block events for. that's it, that's the whole argument. she's low maintenance 💅

🌸 DESCRIPTION 🌸

okay so here's the tea. the moment this function returns, it is guaranteed that event checking isn't in progress and won't happen until you unblock it with disk_unblock_events. like, you literally have the receipts.

and the blocking is counted, bestie — it's giving bouncer with a clicker. the actual unblocking only happens after the matching number of unblocks are done, so don't try to skip the line. 🔥

🫶 heads up though: this intentionally does not block event checking from disk_clear_events. she has her own thing going on and we respect it.

🦋 CONTEXT 🦋

Might sleep. 😴 iykyk — plan accordingly, she is not about to be fine with you calling her somewhere she can't nap.
