This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:
commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")
The refactoring is going to alter the default behavior of
alloc_workqueue() to be unbound by default.
With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU. For more details see the Link tag below.
In order to keep alloc_workqueue() behavior identical, explicitly request
WQ_PERCPU.

Module parameters for timeouts are a poor interface choice as they
affect all device instances globally rather than being configurable
per file descriptor.
The current implementation also returns -EAGAIN on timeout, requiring
userspace to implement retry loops around blocking operations.

commit adds poll() support, allowing applications to implement timeout
handling using standard poll()/select() interfaces.
