Subject: Two sched patchs missing from 4.4-stable: inclusion possible?
Date: Thu, 18 May 2017 11:11:23 +0200 [thread overview]
Message-ID: <CACaSxvbptarOqNTD058eoxbxb770NiK70PaoYRvwW1MkBRX-2w@mail.gmail.com> (raw)
Hello,
The following two patches series, merged in mainline 4.7, was Cc'ed to stable@,
but somehow didn't made its way to the 4.4.x stable tree:
754bd598be9bbc953bc709a9e8ed7f3188bfb9d7
094f469172e00d6ab0a3130b0e01c83b3cf3a98d

https://marc.info/?l=linux-kernel&m=146608185431676
https://marc.info/?l=linux-kernel&m=146608184031673
This patch series address a real life issue, ie. we're seeing an
oopsing machine about every day on a kubernetes cluster, and
other users reported the same problem, for instance :
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1687512
https://github.com/kubernetes/kops/issues/874
Those two patches are also on their way for inclusion in the current
(4.4 based) LTS Ubuntu release :
https://code.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/xenial/+ref/master-next
Could this series be considered for 4.4-stable inclusion by any chance ?
For ref, the stacktrace I'm getting on an unpatched 4.4.67 kernel:
