Encrypted file extents now have the 'encryption' field set to an
encryption type. Let's print it.

May I ask why preallocated file extent would have encryption value set?
My common sense says that encryption policy should only be set for
regular file extents.
There's nothing wrong with pre-allocating encrypted files. Unlike
compression, the exact size is known beforehand.
IN that case, does it mean even a hole will have encryption value set?
This looks weird. Is there any special reason for setting encryption
value for hole/preallocated range?
Can't we only set the encryption value only for regular,
non-preallocated extents?
Thanks,
Qu
Simillar to NOCOW, the encrypted data will be stored with the next write.
