This is make applications that uses |waitpid() (and clone(CLONE_CHILD_SETTID)) wake while waiting for the |child to terminate. Given that apps should not mix futex() and futex2(), |any correct app will trigger a harmless noop wakeup on the interface |that it isn't using. | |Signed-off-by: André Almeida |--- | |This commit is here for the intend to show what we need to do in order |to get a full NPTL working on top of futex2. It should be merged after |we talk to glibc folks on the details around the futex_wait() side. For |instance, we could use this as an opportunity to use private futexes or |8bit sized futexes, but both sides need to use the exactly same flags. |--- | include/linux/syscalls.h | 2 ++ | kernel/fork.c | 2 ++ | kernel/futex2.c | 30 ++++++++++++++++++------------ | 3 files changed, 22 insertions(+), 12 deletions(-) | |diff --git a/include/linux/syscalls.h b/include/linux/syscalls.h |index c108df6b3b82..94e0356ceeaa 100644 |--- a/include/linux/syscalls.h |+++ b/include/linux/syscalls.h -------------------------- No file to patch.
