FILENAME_MAX is 4096 bytes, I am using a 64bit system.
struct cg_mount_table_s {
char name[FILENAME_MAX];
char path[FILENAME_MAX];
int index;
};
sizeof (cg_mount_table_s) is 8196 (4096+4096+4)
struct cgroup_context_s {
/* size of ptr 8 bytes, 100 controllers = 800 */
char *cg_namespace[CG_CONTROLLER_MAX];
/* 8196 * 100 = 819600 */
struct cg_mount_table_s mount[CG_CONTROLLER_MAX];
/* 4 bytes */
unsigned size;
};
i.e. 819600 + 800 + 4 = 820404 (dont know why it is 4 bytes less)
