Paolo Abeni 2de79ee27f net: try to avoid unneeded backlog flush ... flush_all_backlogs() may cause deadlock on systems running processes with FIFO scheduling policy. The above is critical in -RT scenarios, where user-space specifically ensure no network activity is scheduled on the CPU running the mentioned FIFO process, but still get stuck. This commit tries to address the problem checking the backlog status on the remote CPUs before scheduling the flush operation. If the backlog is empty, we can skip it. v1 -> v2: - explicitly clear flushed cpu mask - Eric Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.
