Subject: [PATCH 1/4] f2fs: don't keep meta pages used for block migration
Date: Fri, 27 Jul 2018 18:15:13 +0800	[thread overview]
Message-ID: <20180727101516.41403-1-yuchao0@huawei.com> (raw)

For migration of encrypted inode's block, we load data of encrypted block
into meta inode's page cache, after checkpoint, those all intermediate
pages should be clean, and no one will read them again, so let's just
release them for more memory.
