H A D | ovl_entry.h | diff 2664bd0897c2889258472a1ee922ef9d4c5fa58f Fri May 11 17:49:30 CEST 2018 Vivek Goyal <vgoyal@redhat.com> ovl: Store lower data inode in ovl_inode
Right now ovl_inode stores inode pointer for lower inode. This helps with quickly getting lower inode given overlay inode (ovl_inode_lower()).
Now with metadata only copy-up, we can have metacopy inode in middle layer as well and inode containing data can be different from ->lower. I need to be able to open the real file in ovl_open_realfile() and for that I need to quickly find the lower data inode.
Hence store lower data inode also in ovl_inode. Also provide an helper ovl_inode_lowerdata() to access this field.
