We have:
int cgroup_migrate_vet_dst(struct cgroup *dst_cgrp)
{
...
/* mixables don't care */
if (cgroup_is_mixable(dst_cgrp))
return 0;
/*
* If @dst_cgrp is already or can become a thread root or is
* threaded, it doesn't matter.
*/
if (cgroup_can_be_thread_root(dst_cgrp) || cgroup_is_threaded(dst_cgrp))
return 0;
...
}
but in fact the entry of cgroup_can_be_thread_root() covers case that
checking cgroup_is_mixable() as following:
static bool cgroup_can_be_thread_root(struct cgroup *cgrp)
{
/* mixables don't care */
if (cgroup_is_mixable(cgrp))
return true;
...
}
so explicitly checking in cgroup_migrate_vet_dst is unnecessary.
