💖 debugfs_create_devm_seqfile(9) 💖

okay so welcome to the Kernel API Manual page for debugfs_create_devm_seqfile, bestie. This is the one where debugfs makes a file that’s bound to a device, and we’re gonna go through every argument like it’s a group project where everyone actually shows up. 💅

✨ NAME ✨

debugfs_create_devm_seqfile — create a debugfs file that is bound to device. No cap, that’s the whole vibe. 🦋

🌸 SYNOPSIS 🌸

void debugfs_create_devm_seqfile (struct device *dev , const char *name
, struct dentry *parent , int (*read_fn)(struct seq_file *s, void *data)
);

🎀 ARGUMENTS 🎀

• dev — the device related to this debugfs file. it’s giving “who is this file for?” energy. ✨
• name — the name of the debugfs file. literally the label on the door. 🚪
• parent — a pointer to the parent dentry for this file. This should be a directory dentry if set. If this parameter is NULL, then the file will be created in the root of the debugfs filesystem. so yeah, NULL means it goes straight to the debugfs root like it owns the place. 👑
• read_fn — function pointer called to print the seq_file content. this is the main character that actually does the printing. 🔥
