* Purpose: To test the meta data entry splitting capability in the page
* buffer (needed to deal with H5FA and H5EA's unfortunate
* design choice of sub-allocating multiple metadata entries
* out of a single file space allocation), we must be able
* to configure the metadata cache to report that the
* current I/O request is for such an entry.
*
* To do this, we must set cache_ptr->curr_io_type to
* point to the instance of H5C_class_t with one such
* client.
*
* This function does this by setting cache_ptr->curr_io_type
* to H5AC_EARRAY_DBLK_PAGE if set_splitable is TRUE, and to
* NULL otherwise.
*
* Needless to say, this is purely a testing function, and
* should not be called otherwise.
*
* Return: void

* Changes: None.
