/**
* glibtop_proc_io:
* @disk_rchar: The number of bytes which this task has caused to be read from storage. This
* is simply the sum of bytes which this process passed to read() and pread(), also including tty IO,
* and it is unaffected by whether or not actual physical disk IO was required.
* @disk_wchar: The number of bytes which this task has caused, or shall cause to be written
* to disk. Similar caveats apply here as with rchar.
* @disk_rbytes: Attempt to count the number of bytes which this process really did cause to
* be fetched from the storage layer. Done at the submit_bio() level, so it is
* accurate for block-backed filesystems.
* @disk_wbytes: Attempt to count the number of bytes which this process caused to be sent to
* the storage layer. This is done at page-dirtying time.
*
* Process disk io data filled by glibtop_get_proc_io().
