[1/2] kernel-shark-2.alpha: Allow appending multiple datafiles from command line

Commit Message

Yordan Karadzhov April 3, 2020, 4:02 p.m. UTC

Multiple data files can be appended using the "-a" command line option.
This can be done with:

kernelshark -i foo -a bar1 -a bar2

or

kernelshark -i foo -a "bar1 bar2"
