Subject: [PATCH v2 26/44] mm/damon: Stop using vma_mas_store() for maple tree
 store

From: "Liam R. Howlett" <Liam.Howlett@...cle.com>

Prepare for the removal of the vma_mas_store() function by open coding
the maple tree store in this test code.  Set the range of the maple
state and call the store function directly.
