Expedited grace periods check dyntick-idle state, and avoid sending IPIs to idle CPUs, including those running guest OSes, and, on NOHZ_FULL kernels, nohz_full CPUs. However, the kernel has been observed checking a CPU while it was non-idle, but sending the IPI after it has gone idle. This commit therefore rechecks idle state immediately before sending the IPI, refraining from IPIing CPUs that have since gone idle. Reported-by: Rik van Riel <riel@redhat.com> Signed-off-by: Paul E.
