* General Notes:
* -------------
* The 'context_id' field of all ioctl structures contains the context
* identifier for a context in the lower 32-bits (upper 32-bits are not

* in its entirety (all 64-bits) is to be treated as an opaque cookie and

* DK_CXLFLASH_ATTACH Notes:
* ------------------------
* Read/write access permissions are specified via the O_RDONLY, O_WRONLY,

* A valid adapter file descriptor (fd >= 0) is only returned on the initial
