[PATCH 0/3] Some exit code tidying

[PATCH 0/3] Some exit code tidying

[Ian Rogers]

I'm interested in varying error codes for things like parse event
failures. This is some cleanup to use more intention revealing names
in the existing exit/test cases.

Ian Rogers (3):
  libperf: Prefer exit(EXIT_SUCCESS) over exit(0)
  tools perf: Prefer exit(EXIT_*) over exit(0|1)
  perf test: Be more consistent in use of TEST_*

[PATCH 3/3] perf test: Be more consistent in use of TEST_*

[Ian Rogers]

The TEST_OK, TEST_FAIL and TEST_SKIP enum values are used
inconsistently. Try to reduce this by swapping constants for enum values
to try to be more intention revealing.

I think it's better to separate changes that do not change the current behaviour
from these changes (0 -> TEST_SKIP) into different patches.

Ack. This is the only case of this I see as TEST_OK would contradict
the debug output. There are also cases where I've swapped things like
-ENOMEM or -EINVAL for TEST_FAIL for things that generally won't
happen like malloc failures - the test calling function doesn't handle
-ENOMEM. Separating all of these out into CLs is work I'd prefer to
avoid, but I agree it makes just eye-balling this as a substitution CL
hard.

Thanks,
Ian
