Package: linux-image-4.10.0-14-generic 4.10.0-14.16~16.04.1
ProcVersionSignature: Ubuntu 4.10.0-14.16~16.04.1-generic 4.10.3

UpgradeStatus: No upgrade log present (probably fresh install) |
== SRU REQUEST [Xenial] ==
We are getting lttng module build failures on the HWE 4.10.0 kernel because we are missing the 4.9 and 4.10 compatibility patches to build for a 4.10 kernel.
== Fix ==
Apply minimal set of upstream patches to enable 4.9 + 4.10 builds:
769b62a02f62ff8db93f109d9f63a1df6ea9990b
Fix-unregister-cpu-hotplug-notifier-on-buffer-alloc-.patch
489de24bfb835022b64c2e71d717eaf333ab3633
Add-load-unload-messages-to-kernel-log.patch
3e86016420272ce5ef0139ad52f20c83305f0f15
Fix-update-scsi-instrumentation-for-4.7-kernels.patch
f3166f27f5e2d2210cec32d68c277940a7473281
btrfs-instrumentation-update-to-4.10-kernel.patch
507143bc5de50c0e5493d63fb5c300fa42326842
timer-instrumentation-adapt-to-ktime_t-without-union.patch
1e36732678d7cc650940b4508031acf2f6ffcd1b
Adapt-lttng-modules-to-Linux-4.10-cpu-hotplug-state-.patch
== Testing ==
Without the fix, lttng modules won't install and build on HWE 4.10 kernels. With the fix, the lttng modules build and also pass the ubuntu kernel team autotest lttng smoke tests.
Should be tested with xenial 4.4 kernel to ensure backward compatibility is not broken on the default Xenial kernels
== Regression potential ==
Can potential break lttng.
