This works, yes, although maybe there should be a way to run tune2fs -l
and traverse its output to either build a return hash (i.e. what
do_tune2fs_l currently does) or just lookup one or more keys (like
needed here).
We could extract running tune2fs -l to separate function returning
char*, and parse parameters using strstr. It's terrible... I think the
cost of calling external command is much higher than the cost of
building hash.
To make things betters, we could extract line-splitting function, create
2 similar functions (1 building hash (as for now) and 1 comparing key to
argument). I do not think we will save much if we avoid copying strings
into hash.
