Functions
void *	debugfs_get_aux (const struct file *file)
: a pointer to a string containing the name of the file to create.
debugfs_create_xul - create a debugfs file that is used to read and write an unsigned long value, formatted in hexadecimal @mode: the permission that the file should have @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. @value: a pointer to the variable that the file should read to and write from.

Variables
struct dentry *	arch_debugfs_dir
static int const char *	fmt
