Subject: [PATCH v2] f2fs: clear victim_secmap when section has full valid blocks
Date: Tue, 24 Jul 2018 17:27:22 +0800 [thread overview]
Message-ID: <1532424442-9867-1-git-send-email-yunlong.song@huawei.com> (raw)
In-Reply-To: <1532355022-163029-1-git-send-email-yunlong.song@huawei.com>
Without this patch, f2fs only clears victim_secmap when it finds out
that the section has no valid blocks at all, but forgets to clear the
victim_secmap when the whole section has full valid blocks.
