[LTP] open posix testsuite and names of testcases

[Jan Stancek <jstancek@redhat.com>]

Hi,

this testsuite has many testcases, where binary name is in format: [number]-[number].run-test
This is not very helpful when trying to find out, which one actually
crashed or which one is responsible for kernel oops/hung tasks.
For example if I get in dmesg:
[  702.018706] 1-5.run-test[10140]: segfault at 7f84e724bed8 ip 0000000000402208 sp 00007f84e724bed0 error 6 in 1-5.run-test[400000+4000]
it's not clear, which testcase is responsible.

Does anyone have some ideas?

I had these two:
1. rename all testcases - lot of work, they are also referenced in some .sh scripts
2. modify run-tests.sh to copy it under more verbose name and run that one

diff --git a/testcases/open_posix_testsuite/bin/run-tests.sh b/testcases/open_posix_testsuite/bin/run-tests.sh
index bd8ca14..ddb6e0b 100755

 	if [ "$ret_code" = "0" ]; then

Which makes logs a bit more helpful:
