Re: [RFC PATCH 26/31] test: lmb: run lmb tests only manually

The LMB code has been changed so that the memory reservations and
allocations are now persistent and global. With this change, the
design of the LMB tests needs to be changed accordingly. For now, mark
the LMB tests to be run only manually. The tests won't be run as part
of the unit test suite, and thus would not interfere with the running
of the rest of the tests.


We should run important tests in the CI.

You could trigger the 'manual' test from a Python test and reboot the
system to get into an initial state.

Best regards

Heinrich
