[PATCH RFC DRAFT v2 01/13] fs: add fscrypt offset

[Christian Brauner]

Store the offset of the fscrypt data pointer from struct inode in struct
inode_operations. Both are embedded in the filesystem's private inode.

This will allow us to drop the fscrypt data pointer from struct inode
itself and move it into the filesystem's inode.
