The FILE_SPREAD_SLAB flag is used by cpuset.memory_spread_slab with read/write operations:
In kernel/cgroup/cpuset.c,
static struct cftype legacy_files[] = {
... snip ...
{
.name = "memory_spread_slab",
.read_u64 = cpuset_read_u64,
.write_u64 = cpuset_write_u64,
.private = FILE_SPREAD_SLAB,
},
... snip ...
};
