Re: [PATCH v2 2/2] mm/damon/vaddr: Add 'nr_piece == 1' check in damon_va_evenly_split_region()

Hi Zheng,

Cc-ed kunit folks, as we usually do for DAMON kunit test changes.

As discussed in [1], damon_va_evenly_split_region() is called to size-evenly split a region into 'nr_pieces' small regions, when nr_pieces == 1, no actual split is required. Check that case for better code readability and add a simple kunit testcase.
