[Ocfs2-devel] SEEK_DATA/HOLE on ocfs2 - v2

[Sunil Mushran]

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.

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.
