workqueue: skip the node_nr_active update for non-unbound workqueuesgrafted
apply_wqattrs_commit() updates node_nr_active->max unconditionally. wq->node_nr_active[] is only allocated for unbound workqueues, so guard the call before per-cpu workqueues start using this path. No functional change: only unbound workqueues reach apply_wqattrs_*() today. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Tejun Heo <tj@kernel.org>

+ depends on HAS_IOMEM
+ help
+ Dallas' 1-wire bus is useful to connect slow 1-pin devices
+ such as iButtons and thermal sensors.
+
+ If you want W1 support, you should say Y here.
+
+ This W1 support can also be built as a module. If so, the module
+ will be called wire.

+ bool "Userspace communication over connector"
+ default y
+ help
+ This allows to communicate with userspace using connector. For more
+ information see <file:Documentation/driver-api/connector.rst>.
+ There are three types of messages between w1 core and userspace:
+ 1. Events. They are generated each time new master or slave device found
+ either due to automatic or requested search.
+ 2. Userspace commands. Includes read/write and search/alarm search commands.
+ 3. Replies to userspace commands.
