From 89d347a545a704e0bd4fc61f9aea956d71bc72d2 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Mon, 19 Feb 2024 11:44:21 -0800 Subject: mm/damon/core: remove ->goal field of damos_quota DAMOS quota auto-tuning feature supports static signle goal and dynamic multiple goals via DAMON kernel API, specifically via ->goal and ->goals fields of damos_quota struct, respectively. All in-tree DAMOS kernel API users are using only the dynamic multiple goals now. Remove the unsued static single goal interface.
