[PATCH v3 01/13] fs: add fscrypt offset

2025-07-22T19:27:55Z

Store the offset of the fscrypt data pointer from struct inode in struct
super_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.
