Subject: netsched: Allow var_sk_bound_if meta to work on all namespaces
X-Git-Tag: firefly_0821_release~9833^2~3968^2~278
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2939e275994977b6c9eb7fd082b7b0caa35b96b0;p=firefly-linux-kernel-4.4.55.git

netsched: Allow var_sk_bound_if meta to work on all namespaces

This fix can probably wait 2.6.33, or should use another patch
if needed in 2.6.32 (no get_dev_by_index_rcu() before 2.6.33)
