Comment(by bigorneault):
Support for private futexes was added in 2.6.22, while support for the
FUTEX_CLOCK_REALTIME flag was added in 2.6.29.
To confirm that this is an issue with the futex support, I built glibc
with --enable-kernel=2.6.22.5 and adjusted manually the following #define:
1 - 2.6.22 to 2.6.28: tests fails.
#define __ASSUME_PRIVATE_FUTEX 1
#undef __ASSUME_FUTEX_CLOCK_REALTIME
2 - anything before 2.6.22: All tests pass.
#undef __ASSUME_PRIVATE_FUTEX
#undef __ASSUME_FUTEX_CLOCK_REALTIME
3 - anything later that 2.6.29: All tests pass.
#define __ASSUME_PRIVATE_FUTEX 1
#define __ASSUME_FUTEX_CLOCK_REALTIME 1
Maybe removing the futex from the kernel configuration could also fix this
issue (need to be tested).
