Several cgroup bug fixes. * cgroup core was calling a migration callback on empty migrations, which could make cpuset crash. * There was a very subtle bug where the controller interface files aren't created directly when cgroup2 is mounted. Because later operations create them, this bug didn't get noticed earlier. * Failed writes to cgroup.subtree_control were incorrectly returning 0. The following changes since commit cee37d83e6d9ada1c2254c73bac7955f9e048d22: Merge branch 'work.read_write' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs (2017-07-07 21:48:15 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git for-4.13-fixes for you to fetch changes up to 3c74541777302eec43a0d1327c4d58b8659a776b: cgroup: fix error return value from cgroup_subtree_control() (2017-07-23 08:15:17 -0400) ---------------------------------------------------------------- Tejun Heo (3): cgroup: don't call migration methods if there are no tasks to migrate cgroup: create dfl_root files on subsys registration cgroup: fix error return value from cgroup_subtree_control() kernel/cgroup/cgroup-internal.h | 3 ++ kernel/cgroup/cgroup.c | 66 +++++++++++++++++++++++------------------ 2 files changed, 40 insertions(+), 29 deletions(-) -- tejun
