From 34403fa579514a6de378f06f79239821c92305bf Mon Sep 17 00:00:00 2001 From: "Liam R. Howlett" Date: Fri, 20 Jan 2023 11:26:31 -0500 Subject: mm/damon/vaddr-test.h: stop using vma_mas_store() for maple tree store 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. Link: https://lkml.kernel.org/r/20230120162650.984577-31-Liam.Howlett@oracle.com Signed-off-by: Liam R.
