Subject: [PATCH 65/72] zdtm: print errno info when accessing *.out failure
|
|
|
|
The line `Output file *.out appears to exist, aborting` is confusing.
|
|
The one common reason is permission denied because of the test desc
|
|
is lack of suid flag. The zdtm.py will set `ZDTM_UID` and `ZDTM_GID`,
|
|
the function `test_init()` (in `zdtm/lib/test.c`) will change tester
|
|
itself to that uid and gid if no suid flag.
|
|
|
|
Here print the errno when access *.out failed.
