Smaller patches are always
Hi Steve,
I took a closer look at this, and I'm thinking now that its simpler to
just take the >i_mutex in sched_feat_write(), surrounding the
test/set jump_label call. It should be about 3 lines :)
I started re-working this with the patches in this series and it just
seemed like a lot of code
Hi Steve,
I took a closer look at this, and I'm thinking now that its simpler to
just take the inode-i_mutex in sched_feat_write(), surrounding the
test/set jump_label call. It should be about 3 lines :)

Cleaning out my INBOX I found this patch series. It seems to have been
forgotten about. It ended up with Ingo and Peter agreeing with the way
things should be done and I thought Jason was going to send an update.
But that seems to never have happened.
Does this patch series still look legit?
Cleaning out my INBOX I found this patch series. It seems to have been
forgotten about. It ended up with Ingo and Peter agreeing with the way
things should be done and I thought Jason was going to send an update.
But that seems to never have happened.

Hi,
As pointed out by Andi Kleen, some static key users can be racy because they
check the value of the key->enabled, and then subsequently update the branch
