Amir Goldstein 18e48d0e2c ovl: store upper real file in ovl_file struct ... When an overlayfs file is opened as lower and then the file is copied up, every operation on the overlayfs open file will open a temporary backing file to the upper dentry and close it at the end of the operation. Store the upper real file along side the original (lower) real file in ovl_file instead of opening a temporary upper file on every operation.
