 Subsystems and drivers can create and queue work items through special
 workqueue API functions as they see fit. They can influence some
 aspects of the way the work items are executed by setting flags on the
 workqueue they are putting the work item on. These flags include
-things like CPU locality, reentrancy, concurrency limits and more. To

-Each gcwq bound to an actual CPU implements concurrency management by

 Keeping idle workers around doesn't cost other than the memory space
 for kthreads, so cmwq holds onto idle ones for a while before killing
 them.
 
 For an unbound wq, the above concurrency management doesn't apply and

 bound wq to ignore the concurrency management.  Please refer to the
 API section for details.
