I am terrible with names. It's short for Mutual eXclusion. Can of course be spelled out if preferred. [snip] > Apologies, I've not had a chance to apply and try this yet.

No, this selftest terminates. The script, tools/testing/selftests/locking/mx_test.sh, is written to be robust wrt. module load/unload failures. The reason I prefer to run it as module, is the turn-around time. From an edit, it takes literally only a second to compile the module out-of-tree, another second to copy it to the *updates* on the test server. But if the community prefers that all the tests are run when the test is built-in, the loop looping though the eligible tests can be moved from the script to the C source instead. Thxs, Håkon
