Add 'stats-dump' file to exported checkpoint
There was the question about how long it takes to create a checkpoint. CRIU already provides some statistics about how long it takes to create a checkpoint and similar. With this change the file 'stats-dump' is included in the checkpoint archive and the tool checkpointctl can be used to display these statistics: ./checkpointctl show -t /tmp/cp.tar --print-stats Displaying container checkpoint data from /tmp/dump.tar [...] CRIU dump statistics +---------------+-------------+--------------+---------------+---------------+---------------+ | FREEZING TIME | FROZEN TIME | MEMDUMP TIME | MEMWRITE TIME | PAGES SCANNED | PAGES WRITTEN | +---------------+-------------+--------------+---------------+---------------+---------------+ | 105405 us | 1376964 us | 504399 us | 446571 us | 492153 | 88689 | +---------------+-------------+--------------+---------------+---------------+---------------+ Signed-off-by: Adrian Reber <areber@redhat.com>
