Hello Greg, I am writing to report some questions when working on my kernel tree.
1. About this patch (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/comm...), as Ben has already pointed out in 4.4 tree, it only fixes an issue in 4.7. So I guess this should be reverted in 3.18 as well?
2. About this patch (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/comm...), in 3.16 tree Ben modifies common_timer_get() as well. The difference I can see is the check for SIGEV_THREAD_ID, so would there be some issues if we don't change them?
3. About this patch (https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/comm...), it seems like you directly pick it from upstream, but we have another "goto fail" compared to upstream, which means we should free eps[0].ring it in failure path additionally, I guess?
Thanks in advance, sorry for too much questions.
