Name:cgroup_init_cftypes

Proto:static int cgroup_init_cftypes(struct cgroup_subsys *ss, struct cftype *cfts)

Type:int

Parameter:

TypeParameterName
struct cgroup_subsys *ss
struct cftype *cfts

3963  Return -ENOMEM
3965  * write() is bounced through kernel buffer. If atomic_write_len * is not set, a write larger than PAGE_SIZE results in partial * operations of PAGE_SIZE chunks. If atomic_write_len is set, * writes upto the specified size are executed atomically but * larg = The maximum length of string, excluding trailing nul, that can* be passed to write. If < PAGE_SIZE-1, PAGE_SIZE-1 is assumed.
