 * remain unused and the memory is wasted. In contrast, when the block size is
 * 16, the average unused memory per file is only 8 bytes. However, it requires
 * more allocations for the same size file and thus more overhead per block for
 * the dynamic memory management.
 *
 * Second, the block size has an impact on the maximum size file that can be
 * stored in the IMFS. With smaller block size, the maximum file size is
 * correspondingly smaller. The following shows the maximum file size possible
 * based on the configured block size:
 *
 * * when the block size is 16 bytes, the maximum file size is 1,328 bytes.

 *   Processor Affinity Priority SMP Scheduler</a> which can be configured
 *   through the #CONFIGURE_SCHEDULER_PRIORITY_AFFINITY_SMP configuration
 *   option
 *
 * this configuration option specifies the maximum numeric priority of any task
 * for these schedulers and one less that the number of priority levels for
 * these schedulers.  For all other schedulers provided by RTEMS, this
 * configuration option has no effect.
 *
 * @par Default Value
 * The default value is 255.
 *
 * @par Value Constraints
 * The value of this configuration option shall be equal to 3, 7, 31, 63, 127,
 * or 255.
 *
 * @par Notes
 * @parblock
 * The numerically greatest priority is the logically lowest priority in the
 * system and will thus be used by the IDLE task.
 *
 * Priority zero is reserved for internal use by RTEMS and is not available to
 * applications.
 *
 * Reducing the number of priorities through this configuration option reduces
 * the amount of memory allocated by the schedulers listed above.  These
 * schedulers use a chain control structure per priority and this structure
 * consists of three pointers.  On a 32-bit architecture, the allocated memory
 * is 12 bytes * (``CONFIGURE_MAXIMUM_PRIORITY`` + 1), e.g. 3072 bytes for 256
 * priority levels (default), 48 bytes for 4 priority levels
 * (``CONFIGURE_MAXIMUM_PRIORITY == 3``).
 *
 * The default value is 255, because RTEMS shall support 256 priority levels to
 * be compliant with various standards.  These priorities range from 0 to 255.
