[sos-devel] [PATCH 1/2] [plugin] allow reverse ordering in add_copy_spec_limit

[Sandro Bonazzola]

Added parameter to add_copy_spec_limit for allowing
to use reverse ordering while collecting files.
Without this time-stamped log files will be collected
always starting from oldest so most recent logs wasn't
in the report.
