DEBUGFS_CREATE_DIR(9)                 The debugfs filesystem                DEBUGFS_CREATE_DIR(9)



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.
