• The new implementation directly writes panic.message() without handling the None case, which may lead to unexpected output. Consider preserving the original match to provide an appropriate fallback error message if panic.message() returns None.

match panic.message() {

The variable 'alloc' is used here but it is not defined in the function; it should likely be 'frame_alloc' as used earlier.

Suggested change

	let pd = match pdpt.create_next_table(virt, alloc) {
	let pd = match pdpt.create_next_table(virt, frame_alloc) {

There is a spelling error in the log message: "hudge" should be corrected to "huge".

Suggested change

	tracing::trace!("page is hudge");
	tracing::trace!("page is huge");
