[PATCH 2/5] ipc/sem: rework task wakeups

Our sysv sems have been using the notion of lockless wakeups for a while, ever since 0a2b9d4c796 (ipc/sem.c: move wake_up_process out of the spinlock section), in order to reduce the sem_lock hold times. This in-house pending queue can be replaced by wake_q (just like all the rest of ipc now), in

The compiler already does this, but make it explicit. This helper is really small and also used in update_queue's main loop, which is O(N^2) scanning. Inline and avoid the function overhead. Signed-off-by: Davidlohr Bueso --- ipc/sem.c | 2 +- 1 file changed, 1 insertion(+), 1

[PATCH 3/5] ipc/sem: optimize perform_atomic_semop()

This is the main workhorse that deals with semop user calls such that the waitforzero or semval update operations, on the set, can complete on not as the sma currently stands. Currently, the set is iterated twice (setting semval, then backwards for the sempid value). Slowpaths, and particularly

[PATCH -next 0/5] ipc/sem: semop(2) improvements

Hi, Here are a few updates around the semop syscall handling that I noticed while reviewing Manfred's simple vs complex ops fixes. Changes are on top of -next, which means that Manfred's pending patches to ipc/sem.c that remove the redundant barrier(s) would probably have to be rebased. The
