In practice this is already happening through the unbound ice_service_timer that may fire anywhere and queue the workqueue accordingly to any CPU. > > Make this official so that the ice workqueue is only ever queued to housekeeping CPUs on nohz_full. > > Signed-off-by: Frederic Weisbecker <frederic@kernel.org> > --- > Resend of: https://lore.kernel.org/all/20240922222420.18009-1-frederic@kernel.org/ > - Added IWL and netdev lists > > drivers/net/ethernet/intel/ice/ice_main.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > Tested-by: Pucha Himasekhar Reddy <himasekharx.reddy.pucha@intel.com> (A Contingent worker at Intel)
