    cgroup: remove sane_behavior support on non-default hierarchies · aa6ec29b
    Tejun Heo authored
    sane_behavior has been used as a development vehicle for the default
    unified hierarchy.  Now that the default hierarchy is in place, the
    flag became redundant and confusing as its usage is allowed on all
    hierarchies.  There are gonna be either the default hierarchy or
    legacy ones.  Let's make that clear by removing sane_behavior support
    on non-default hierarchies.
    This patch replaces cgroup_sane_behavior() with cgroup_on_dfl().  The
    comment on top of CGRP_ROOT_SANE_BEHAVIOR is moved to on top of
    cgroup_on_dfl() with sane_behavior specific part dropped.
    On the default and legacy hierarchies w/o sane_behavior, this
    shouldn't cause any behavior differences.
