Subject[PATCH 0/3] ipc/sem.c: multiple fixes
Date
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?
