From 4a20865b0744c987655472425203345d970da7a0 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Tue, 22 Mar 2022 14:49:01 -0700 Subject: [PATCH] mm/damon/dbgfs: use operations id for knowing if the target has pid DAMON debugfs interface depends on monitoring operations for virtual address spaces because it knows if the target has pid or not by seeing if the context is configured to use one of the virtual address space monitoring operation functions. We can replace that check with 'enum damon_ops_id' now, to make it independent. This commit makes the change.
