Subject: [patch 17/21] selftests/damon: split test cases
Date: Fri, 10 Dec 2021 14:46:59 -0800 [thread overview]
Message-ID: <20211210224659.U3T9o0WbW%akpm@linux-foundation.org> (raw)
In-Reply-To: <20211210144539.663efee2c80d8450e6180230@linux-foundation.org>
From: SeongJae Park <sj@kernel.org>
Subject: selftests/damon: split test cases
Currently, the single test program, debugfs.sh, contains all test cases
for DAMON. When one of the cases fails, finding which case is failed from
the test log is not so easy, and all remaining tests will be skipped. To
improve the situation, this commit splits the single program into small
test programs having their own names.
