| From | Miklos Szeredi <> | Subject | [RFC PATCH 07/35] ovl: copy up file size as well | Date | Thu, 12 Apr 2018 17:07:58 +0200 |
| |
Copy i_size of the underlying inode to the overlay inode in ovl_copyattr().
This is in preparation for stacking I/O operations on overlay files.
This patch shouldn't have any observable effect.
