bd_finish_claiming(9) 💅

okay so this is the bd_finish_claiming(9) page from the Kernel API Manual — yes bestie, the manual name is literally Kernel API Manual, and we're folding it in right here at the top. This whole page is about finishing the claiming of a block device. Slay.

🎀 NAME 🎀

bd_finish_claiming — finish claiming of a block device. Periodt.

✨ SYNOPSIS ✨

void bd_finish_claiming (struct block_device *bdev , void *holder ,
       const struct blk_holder_ops *hops );

🫶 ARGUMENTS 🫶

• bdev — block device of interest. The device we're obsessed with.
• holder — holder that has claimed bdev. The claimant, the main character of this claim.
• hops — block device holder operations. The ops vibe.

💅 DESCRIPTION 💅

Finish exclusive open of a block device. Mark the device as exlusively open by the holder (yes, that spelling is in the source — don't come for me, I'm just the messenger 💀) and wake up all waiters for exclusive open to finish. That's it, that's the whole glow-up: exclusive open gets finished, the holder gets the mark, and the waiters get woken. ✨
