For at least the past couple of days tests of libhugetlbfs have been hanging on mustang in the mlock test running ARMv8 defconfig with both 32 bit and 64 bit userspace - after the mprotect test (the one before it) we get no console output for several hours so it appears that the test has deadlocked. The tail of the log is:
| find_path (2M: 64): PASS | unlinked_fd (2M: 64): PASS | readback (2M: 64): PASS | truncate (2M: 64): PASS | shared (2M: 64): PASS | mprotect (2M: 64): PASS and then a timeout. This may be a generic bug but my ability to run these tests on other platforms with huge page support using the infrastructure I'm using is limited so I've not been able to test elsewhere and confirm.
