| # Simple permission check on hard links. |
| # |
| # Overlayfs had a bug that hardlinks don't share inode, if chmod/chown/etc. |
| # is performed on one of the links then the inode belonging to the other |
| # one won't be updated. The following patch fixed this issue |
| # |
| # 51f7e52 ovl: share inode for hard link |
