ocfs2: implement the VFS clone_range, copy_range, and dedupe_range features Connect the new VFS clone_range, copy_range, and dedupe_range features to the existing reflink capability of ocfs2. Compared to the existing ocfs2 reflink ioctl We have to do things a little differently to support the VFS semantics (we can clone subranges of a file but we don't clone xattrs), but the VFS ioctls are more broadly supported. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> --- v2: Convert inline data files to extents files before reflinking, and fix i_blocks so that stat(2) output is correct. v3: Make zero-length dedupe consistent with btrfs behavior. v4: Use VFS double-inode lock routines and remove MAX_DEDUPE_LEN.
