Hello,
Applied 1-2 to cgroup/for-7.3-fixes with the comment above kill_seq
updated as Shakeel suggested:
--- a/include/linux/cgroup-defs.h
+++ b/include/linux/cgroup-defs.h
@@ -527,7 +527,10 @@ struct cgroup {
int nr_threaded_children; /* # of live threaded child cgroups */
- /* sequence number for cgroup.kill, serialized by css_set_lock. */
+ /*

+ * and css_set_lock held. Readers hold either one.

unsigned int kill_seq;
struct kernfs_node *kn; /* cgroup kernfs entry */
Thanks.
