Subject: [PATCH] f2fs: free_user_blocks should use reserved_segments instead
Date: Mon, 14 Aug 2017 17:22:32 +0800	[thread overview]
Message-ID: <1502702552-78497-1-git-send-email-yunlong.song@huawei.com> (raw)

The part (overprovision_segments - reserved_segments) can still be used for LFS,
so free_use_blocks should use reserved_segments instead, rather than use
overprovision_segments.
