Ping...
move_data_block misses set_cold_data, then the F2FS_WB_CP_DATA will
lack these data pages in move_data_block, and write_checkpoint can
not make sure this pages committed to the flash.

Hmm.. data block migration is running based on meta inode, so it will
be safe since checkpoint will flush all meta pages including encrypted
pages cached in meta inode?

Here, we write encrypted_page back, which belong to meta mapping.
