Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: The nohz_full code in older versions of the MRG-RT kernels was broken and incomplete. Until recently that feature was not enabled because of the way the old nohz_full code interacted with the real time features in the kernel. Consequence: When it was decided to enable the nohz_full feature, the code did not work as expected. Fix: Update the kernel to a newer version. Result: The nohz_full feature works as expect and interacts well with the real time features enabled in the MRG-RT kernel.
