The mmap and truncate patches were basically the same for each filesystem, but
yes it's fine for them to go in separately. Richard, can you take for ubifs:
ubifs: don't bother checking for encryption key in ->mmap()
ubifs: require key for truncate(2) of encrypted file
and Ted can you take for ext4:
ext4: don't bother checking for encryption key in ->mmap()
ext4: require key for truncate(2) of encrypted file
