device name to *mp?

[Soon-Son Kwon <kss@xxxxxxxx>]

Hi, I would like to implement a function that
returns the mount point information pointer
(xfs_mount_t *mp) for a specified device.

For example, if /dev/hda1 is formatted as XFS and
mounted on /mnt, that mount information should
be stored somewhere in the memory and I think it is
xfs_mount_t structure.

So, I would like to find that xfs_mount_t for a specified
device. Can anyone let me know if there is existing
function for that purpose or how to implement it?

Thanks very much....
