Cover letter [PATCH v2 0/2] overlayfs: Handle metacopy mount option better

This is V2 of the patch I had posted. Right now if user passes metacopy=on and if redirect_dir=on is not specified, metacopy is disabled automatically and a messages is sent to console/logs.

This might be little surprising for user. A better behavior probably is to return an error if metacopy can't be enabled. Two patches in the series take care of that.
