Prefer mapfile or read -a to split
command output (or quote to avoid splitting).
We know the behaviour of commands that break the SC2207 rule.
They shouldn't invoke the shell's sloppy word splitting and glob expansion.
E.g. Code: stats=($(cat /sys/block/$dev/stat))
according to SC2207 rule could look like:
IFS=" " read -r -a stats <<< "$(cat /sys/block/$dev/stat))"
Stat file contains one simple line with entries separated by commas
so present code is enough to define statistics for dev.
