The cve-2015-7550 test is actually test "keyctl02" under syscalls/keyctl/ directory. This was the only time we got an error for this test and the binary did not finish its execution (or ran) at all. In other runs you can find "keyctl02" command output:
like: https://lkft.validation.linaro.org/scheduler/job/364398 with: "keyctl02.c:97: PASS: Bug not reproduced"
But, for this particular run, there is no output for keyctl02 and keyctl03. This could be a hang in the process testing the race condition, so the test would have never finished (specially considering this is QEMU). IMO we should wait for another failure like this and check if keyctl02 is hanging and why. Opinions ?
