As a fix for code present in net this should probably be targeted at net (or iwl-net?) rather than net-next. But perhaps there is no need to repost just to address that. > --- > drivers/net/ethernet/intel/ice/ice_common.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/net/ethernet/intel/ice/ice_common.c b/drivers/net/ethernet/intel/ice/ice_common.c > index 6fb0c1e8ae7c..5005c299deb1 100644 > --- a/drivers/net/ethernet/intel/ice/ice_common.c > +++ b/drivers/net/ethernet/intel/ice/ice_common.c > @@ -1885,7 +1885,7 @@ void ice_release_res(struct ice_hw *hw, enum ice_aq_res_ids res) > /* there are some rare cases when trying to release the resource > * results in an admin queue timeout, so handle them correctly > */ > - timeout = jiffies + 10 * ICE_CTL_Q_SQ_CMD_TIMEOUT; > + timeout = jiffies + 10 * usecs_to_jiffies(ICE_CTL_Q_SQ_CMD_TIMEOUT); > do { > status = ice_aq_release_res(hw, res, 0, NULL); > if (status != -EIO) I agree this minimal change is appropriate as a bug fix. But I think that it would be good to provide a follow-up that reworks this code a bit to to use read_poll_timeout(). As per the aim of the cited commit. This should be targeted at net-next (or iwl-next?). Once this bug fix propagates to in net-next. Reviewed-by: Simon Horman
