I will separate the bug fixes into an independent patchset so you can pick them up more easily. Please note that the arm64 crash hotplug feature depends on these fixes, so they need to land first. I will send out the split patches soon. > > I'm currently rolling out crashdump CMA across the Meta fleet, so > right now I care mostly about picking up isolated bug fixes. As it > stands, it's difficult to tell which patches are fixes and which > are features. Only the last three patches are related to the feature, and all the preceding patches are bug fixes. I will separate them out. -- Best regards, Jinjie
