Subject: [PATCH 4/6] mm: compaction: only set skip flag if cc->no_set_skip_hint is false
Date: Thu, 25 May 2023 20:53:59 +0800 [thread overview]
Message-ID: <0eb2cd2407ffb259ae6e3071e10f70f2d41d0f3e.1685018752.git.baolin.wang@linux.alibaba.com> (raw)
In-Reply-To: <cover.1685018752.git.baolin.wang@linux.alibaba.com>
To keep the same logic as test_and_set_skip(), only set the skip flag
if cc->no_set_skip_hint is false, which makes code more reasonable.
