eval.c cases -- agreed.  Now marked as RTEMS_DEBUG with better comment.
Removing from Explanations.txt.

> * scanInt

> * IMFS_print_jnode

This unfortunately has to be tested.  You will have to declare a IMFS_jnode_t
and set the link field to a value > 6.

> * IMFS_unlink

This unfortunately needs to be tested.  Again declare a IMFS_jnode_t.  Set
the node->type == IMFS_HARD_LINK and the node->info.hard_link.link_node to
NULL.

> * IMFS_unmount ( 2 cases )

These are probably direct calls also but need to be tested.  You will have
to declare an instance of rtems_filesystem_mount_table_entry_t and set
the fields as needed to make it fail.

There are the comments.  Should be easy cases just weird and bypassing public
APIs.
