/* Used by MODS_ESC_RESERVE_ALLOCATION, MODS_ESC_GET_RESERVED_ALLOCATION,
* and MODS_ESC_RELEASE_RESERVED_ALLOCATION ioctls.
*
* MODS_ESC_RESERVE_ALLOCATION permits the reservation of a memory allocation
* specified by 'memory_handle' with the tag 'tag'. The 'tag' can take on
* values between 1 and MODS_MEM_MAX_RESERVATIONS and is used to index
* reservations.
*
* MODS_ESC_GET_RESERVED_ALLOCATION is used to claim ownership of a reservation
* specified by 'tag'. If an unclaimed reservation is found using 'tag',
* 'memory_handle' will be populated with the allocation handle.
*
* MODS_ESC_RELEASE_RESERVED_ALLOCATION is used to completely free and stop the
* usage of a memory reservation made through MODS_ESC_RESERVE_ALLOCATION or
* obtained through MODS_ESC_GET_RESERVED_ALLOCATION. The 'tag' is accepted as
* an input to identify the reservation to release. For this ioctl,
* 'memory_handle' is unused.
*
* Limitations include:
* - Only one client may own a reservation at any given time
* - The client reserving the allocation automatically owns the reservation
* - There are two ways to "unclaim" a reservation without freeing the memory:
* 1. Calling MODS_ESC_FREE_PAGES with the associated handle
* 2. Closing a client
