Subject: [PATCH] f2fs: fix heap mode to reset it back
Date: Mon, 29 Jan 2018 11:37:45 +0800	[thread overview]
Message-ID: <1517197065-156255-1-git-send-email-yunlong.song@huawei.com> (raw)

Commit 7a20b8a61eff81bdb7097a578752a74860e9d142 ("f2fs: allocate node
and hot data in the beginning of partition") introduces another mount
option, heap, to reset it back. But it does not do anything for heap
mode, so fix it.
