netfs_start_io_write(9)

okay bestie, welcome to the netfs_start_io_write(9) page from the Kernel API Manual — manual name folded in right here like a little name tag, because we are nothing if not organized. 🎀✨

🌸 NAME 🌸

netfs_start_io_write — declare the file is being used for buffered writes. that's the whole assignment, bestie. 💅

✨ SYNOPSIS ✨

int netfs_start_io_write (struct inode *inode );

🦋 ARGUMENTS 🦋

• inode — file inode. literally just the file inode, no extra lore. 🫶

💖 DESCRIPTION 💖

so this one declares that a buffered read operation is about to start, and it ensures that we block all direct I/O. yes, the NAME says “buffered writes” and the description says “buffered read” — I am not fixing it, I am reporting it. 💀

this is giving “read/write energy is a little chaotic today,” but the facts are the facts: buffered read operation about to start, and all direct I/O gets blocked. periodt. 🚫💅
