Description
It would be nice to have support for renameat2()'s linux specific flags RENAME_WHITEOUT so that Lustre could be safely used as a backend to some overlayfs implementations in user space.
The WHITEOUT directory entry is used to "erase" the presence of an identically-named entry in the underlying filesystem, so that it doesn't appear in ls/readdir output.
