* There are three cases to consider:

* that can fit in a pointer) that is used to uniquely identify an open file.
* Opening the same file name should always yield the same file node value
* for as long as the file with that name remains open anywhere in the system.
* </li>
* <li>When the UmFileContextIsUserContext2 is set, the FileContext parameter
* represents the file descriptor. The file descriptor is a void pointer (or
* an integer that can fit in a pointer) that is used to identify an open
* instance of a file. Opening the same file name may yield a different file
* descriptor.

* <li>When the UmFileContextIsFullContext is set, the FileContext parameter
* is a pointer to a FSP_FSCTL_TRANSACT_FULL_CONTEXT. This allows a user mode
* file system to access the low-level UserContext and UserContext2 values.
