Hi all,

The following patchset enable the use of xfstests to test reflink
functionality under ocfs2.  The first patch tests the ability to reflink
into and out of inline-data files on ocfs2.  Patches 2-6 fix various
problems with the tests that came up when qualifying ocfs2.

The last patch maliciously corrupts ext4 and xfs filesystems to
exploit nonexistent checking of i_size in order to coerce Linux into
loading a file with negative size.  It then exploits integer overflows
in the VFS writeback code to hard lock the kernel.  Don't run the tests
in this patch ({shared,xfs}/40[01]) unless you have a fixed kernel (4.10)

Comments and questions are, as always, welcome.
