On the 4th of January we saw the release of Linux 2.6.37, which contains a large XFS update: 67 files changed, 1424 insertions(+), 1524 deletions(-) User visible changes are the new XFS_IOC_ZERO_RANGE ioctl which allows to convert already allocated space into unwritten extents that return zeros on a read,
would you mind describing some scenario that this ioctl can be used. I am just wondering whether ocfs2 can implement it as well.
