ceph_end_io_direct(9)

💅 NAME 💅

okay so this is the ceph_end_io_direct(9) page from the Kernel API Manual, and honestly? Short, sweet, iconic. The name is literally ceph_end_io_direct — declare that the direct i/o operation is done. That's the whole vibe, bestie. 💖

✨ SYNOPSIS ✨

void ceph_end_io_direct (struct inode *inode );

🎀 ARGUMENTS 🎀

• inode — the file inode, periodt. That's the one and only argument on this page.

🦋 DESCRIPTION 🦋

So here's the tea: you use this to declare that a direct I/O operation is done, and it releases the shared lock on inode->i_rwsem. That's it. No extra lore in this manpage, no hidden side quest — just declare the direct I/O operation done and let that shared lock go. 💅
