Two patches follow this message. One fixes the default implementation
of SEEK_HOLE/DATA. This patch applies atop Josef's last posted patch.
The second patch implements the same on ocfs2.

The test tool for the same is available here.
http://oss.oracle.com/~smushran/seek_data/seek_test.c

It is improved since the last post. It runs cleanly on zfs, ocfs2 and ext3
(default behavior). Users testing on zfs will need to flip the values of
SEEK_HOLE/DATA.

The results on ext4 and btrfs are also available here.

Thanks
