This patch looks OK. I would like to know why the test case for this passes before this is committed. The test code macros that check the return status are supposed to check that this occurs. Is the test written to use assert() and not one of the rtems test support methods?

This should be applied to 4.10 and 4.11 once we know why the test doesn't detect this.

psxsem01 is the test and it provides its own macro to check status. This should be moved to the .h file with the rest of the test status checking macros.

It does check the dispatch disable level but none of the tests check that the allocator mutex is unlocked. Is this something we should add? This is an easy enough mistake to make on create/delete objects.

This is a 4.11 problem.

Add test assertion for allocator mutex being unlocked

The Allocator Mutex should not be locked outside a tested
service call. In an SMP test or heavily multithreaded test,
this is possible since another thread could have the lock
for an extended period of time but this is not the norm
for the tests.

updates 2319.
