2 | tristate "Overlay filesystem support" |
3 | help | |
4 | An overlay filesystem combines two filesystems - an 'upper' filesystem | |
5 | and a 'lower' filesystem. When a name exists in both filesystems, the | |
6 | object in the 'upper' filesystem is visible while the object in the | |
7 | 'lower' filesystem is either hidden or, in the case of directories, | |
8 | merged with the 'upper' object. | |
