debugfs_create_dir: create a directory in the debugfs filesystem
NAME
debugfs_create_dir - create a directory in the debugfs filesystem
SYNOPSIS
-
struct dentry * debugfs_create_dir(const char
* name, struct dentry* parent);
ARGUMENTS
name
-
- a pointer to a string containing the name of the directory to create.
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 directory will be created in the root of the debugfs filesystem.
DESCRIPTION
This function creates a directory in debugfs with the given name.
This function will return a pointer to a dentry if it succeeds. This pointer must be passed to the debugfs_remove function when the file is to be removed (no automatic cleanup happens if your module is unloaded, you are responsible here.) If an error occurs, NULL will be returned.
If debugfs is not enabled in the kernel, the value -ENODEV will be returned.
