Bug Fixes

BZ#1035795
Previously, if the scheduler priority was not specified, the "tuna -t $PID -p OTHER" command failed with the following error:
ValueError: invalid literal for int() with base 10: 'OTHER'
This error occurred also when different parameters, such as RR or FIFO, were passed to the -p option. This bug has been fixed and the value error no longer occurs.
BZ#1059685
Due to a bug in the tuna package, the "tuna -CP" command failed to list processes, returning the following message:
NameError: global name 'cgroups' is not defined
This bug has been fixed and the name error no longer occurs when executing "tuna -CP".
The tuna package has been upgraded to upstream version 0.10.4, which provides a number of bug fixes over the previous version. (BZ#1029591)
Users of tuna are advised to upgrade to these updated packages, which fix these bugs.
