From 74d48dc6ec93223185583db1ddc43edf1e6d3c84 Mon Sep 17 00:00:00 2001 From: Yunlong Song Date: Mon, 29 Jan 2018 11:37:45 +0800 Subject: [PATCH] f2fs: fix heap mode to reset it back 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.
