From 8fa52376da330889a425cc460396d4d2cac18f46 Mon Sep 17 00:00:00 2001 From: SJ Park Date: Tue, 30 Jun 2026 07:17:21 -0700 Subject: [PATCH] selftests/damon/sysfs.sh: test all files in quota goal dir DAMON sysfs interface for DAMOS quota has quite extended since its initial introduction. The test case for that in DAMON sysfs interface essential file operations test (sysfs.sh) has not accordingly extended, though. Extend the test case to test all existing files.
