Hi,
The wakeup scheme used by semtimedop() does not work as intended on -rt. The following series: - fixes one bug that I noticed while thinking about a -rt compatible implementation - prevents the code from returning to user space due to spurious wakeups. (noticed by Peter Zijlstra) - contains a proposal how to support -rt.
Especially the last patch is for discussion - I don't like the overhead introduced by using a completion.
What do you think?
