Test does its checking both after dump and after restore.
Checking is done in the following way:
1. Check that every ps tree process is stopped or dead
2a. SIGKILL every ps tree process if checking after dump
2b. SIGCONT every ps tree process if checking after restore

This series introduces a new fault to emulate a situation
when a file can't be opened by handle and we have to find
it in the irmap cache/
It's required to test irmap cache. I don't know how to force it

Usually we run CRIU tests automatically using Jenkins CI and it reports status
as PASS/FAIL for overall testsuite on used environment. You should dig into log
files to figure out how many tests were failed and skipped. This patch brings
support of cute reports in TAP (Test Anything Protocol) format.
The sample of report:
TAP version 13
1..242
ok 1 - conntracks # SKIP manual run only
ok 2 - busyloop00
ok 3 - sleeping00
ok 4 - pid00
ok 5 - caps00

This is to deal with distros like Arch which take /usr merge to the
