- a pointer to a string containing the name of the file to create.
- the permission that the file should have.

- total number of elements in the array.
This function creates a file in debugfs with the given name that exports array as data. If the mode variable is so set it can be read from. Writing is not supported. Seek within the file is also not supported. Once array is created its size can not be changed.
