Should this be in crash's format?
struct dentry ffffffffffff0000
The format currently used comes from the kernel's own BTF show infrastructure.
crash's struct dentry ffffffffffff0000 syntax is specific to crash. drgn, GDB,
bpftool, and the kernel's own BTF rendering all use the (struct type *)0xaddr
notation we're already using. Adopting crash's format would make this output
inconsistent with all other BTF-based output in the kernel, and would also lose
the member name context (.dentry).
