Subject: [PATCH 2/2] f2fs: fix to do f2fs_balance_fs in f2fs_map_blocks correctly
Date: Sat, 20 Aug 2016 15:12:02 +0800 [thread overview]
Message-ID: <20160820071202.31355-2-yuchao0@huawei.com> (raw)
In-Reply-To: <20160820071202.31355-1-yuchao0@huawei.com>
If we preallocate blocks with f2fs_reserve_blocks in f2fs_map_blocks, we
should call f2fs_balance_fs for checking and reclaiming space, fix it.
