Whilst the tty from proc_t is set to the controling terminal, dev_t
from `struct stat` is set to the Volume Serial Number of the file
processing system. Both are major and minor numbers paried in a single
data type that the driver uses to identify a particular device. However,
the earlier will show you the major and minor numbers of the volume
partition. For example:
8:2 -> MAJOR:MINOR of /dev/sda2
As opposed to the tty from proc_t, that represents the controling
terminal: 136:3 -> MAJOR:MINOR of /dev/pts/3 This is the difference
between the use of procps versus libpstat.
