Regressions (compared to build v4.4.91-48-gc0489dd5896d)
x15 - arm: ltp-syscalls-tests: * fcntl36
* test src: git://github.com/linux-test-project/ltp.gitHm, what does this mean? Did this regress due to a breakage of your system, as this link: https://qa-reports.linaro.org/lkft/linux-stable-rc-4.4-oe/build/v4.4.92/test... shows all "No log available for this test" :(
confused.
There are three issues here:
1. you looked at the wrong link. The board that produced the failure was 'x15' (32-bit ARM), while the test-run you linked to is for 64-bit x86, and fcntl36 did not actually fail there. This is obviously confusing, since we run the same test suite once for each board, and the results are in different places.
2. The "No log available for this test" output here means that the feature to split up the log per test case has not yet been implemented yet. The log is indeed available, you just need to manually look through a large file from the "Log file" link. I also had this problem when I looked at a different regression last week and couldn't find it.
The full log with the LTP output in this case is available for download at https://qa-reports.linaro.org/lkft/linux-stable-rc-4.4-oe/build/v4.4.92/test...
3. The actual failure is here:

I haven't looked at the detailed failure, but the source for that test is available at https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/sysca...
