/* Work queue IDs (indices). These are both zero if there is only one work
* queue.
/* Work queue IDs (indices):
*
* Kernel Work Queues:
* HPWORK: This ID of the high priority work queue that should only be used for
* hi-priority, time-critical, driver bottom-half functions.
*
* LPWORK: This is the ID of the low priority work queue that can be used for any
* purpose. if CONFIG_SCHED_LPWORK is not defined, then there is only one kernel
* work queue and LPWORK == HPWORK.
*
* User Work Queue:
* USRWORK: CONFIG_NUTTX_KERNEL and CONFIG_SCHED_USRWORK are defined, then NuttX
* will also support a user-accessible work queue. Otherwise, USRWORK == LPWORK.
