CONFIG_OVERLAY_FS_METACOPY: Overlayfs: turn on metadata only copy up feature by default

General informations

The Linux kernel configuration item CONFIG_OVERLAY_FS_METACOPY:

Help text

If this config option is enabled then overlay filesystems will copy up only metadata where appropriate and data copy up will happen when a file is opened for WRITE operation. It is still possible to turn off this feature globally with the "metacopy=off" module option or on a filesystem instance basis with the "metacopy=off" mount option.

Note, that this feature is not backward compatible. That is, mounting an overlay which has metacopy only inodes on a kernel that doesn't support this feature will have unexpected results.

If unsure, say N.
