Lawrence Livermore National Labs recently ran the source code
analysis tool Coverity over the e2fsprogs-1.39 source to see
if it would identify any significant bugs. The analysis
turned up 38 mostly minor issues which are enumerated here
with patches. We went through and resolved these issues
but would love to see these mostly minor changes reviewed
and commited upstream.
Thanks,
Brian Behlendorf <behlendorf1@xxxxxxxx>, and
Herb Wartens <wartens2@xxxxxxxx>

Coverity ID: 35: Resource Leak
The memory allocated by string_copy is clearly never reclaimed. The fix adds
free() to the end of the function to reclaim the memory, I didn't see an API
function to free memory allocated by string_copy().
Fixed some whitespace issues as well
