Merge branch 'master' into for-4.4-fixes
The following commit which went into mainline through networking tree 3b13758f51de ("cgroups: Allow dynamically changing net_classid") conflicts in net/core/netclassid_cgroup.c with the following pending fix in cgroup/for-4.4-fixes. 1f7dd3e5a6e4 ("cgroup: fix handling of multi-destination migration from subtree_control enabling") The former separates out update_classid() from cgrp_attach() and updates it to walk all fds of all tasks in the target css so that it can be used from both migration and config change paths. The latter drops @css from cgrp_attach(). Resolve the conflict by making cgrp_attach() call update_classid() with the css from the first task. We can revive @tset walking in cgrp_attach() but given that net_cls is v1 only where there always is only one target css during migration, this is fine.
