💖 inode_to_wb_and_lock_list(9) 💖

okay so bestie, welcome to this little page from the Kernel API Manual — we're talking about inode_to_wb_and_lock_list, and it's giving "find the wb, then lock it" energy. no cap. 🫶

✨ SYNOPSIS ✨

struct bdi_writeback * inode_to_wb_and_lock_list (struct inode *inode );

🎀 ARGUMENTS 🎀

• inode — the inode of interest. that's the one we're looking at, bestie 👀

🌸 DESCRIPTION 🌸

so this is literally the same as locked_inode_to_wb_and_lock_list, except for one iconic little detail: inode->i_lock is not held on entry. nope, not held. don't come in here assuming it is. 💅
