Fix by using a dedicated workqueue. The system_wq's max concurrency limit is being increased separately. - Fix theoretical off-by-one bug when enforcing max cgroup hierarchy depth. ---------------------------------------------------------------- Chen Ridong (1): cgroup/bpf: use a dedicated workqueue for cgroup bpf destruction Xiu Jianfeng (1): cgroup: Fix potential overflow issue when checking max_depth kernel/bpf/cgroup.c | 19 ++++++++++++++++++- kernel/cgroup/cgroup.c | 4 ++-- 2 files changed, 20 insertions(+), 3 deletions(-) -- tejun
