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

config OVERLAY_FS_V1
bool "Overlayfs filesystem (V1) format support"
help
Support the older whiteout format overlayfs filesystems via
the overlay module. This is needed to support legacy kernels
built using the original overlayfs patch set.
