okay so welcome to the Kernel API Manual, bestie — this one is bdev_fput(9) and it's lowkey a little cleanup icon. 💅

🌸 SYNOPSIS 🌸

void bdev_fput (struct file *bdev_file );

🦋 ARGUMENTS 🦋

• bdev_file — open block device. that's the whole vibe check for this arg, no cap. 💖

💫 DESCRIPTION 💫

The important part? Ensure that the block device can be reclaimed before the file is closed — and that file closing is a deferred operation. literally keep that in mind, bestie. 😭✨
