Just call the ioctl directly - fsr is already doing this in a bunch
of places (even has a call to XFS_IOC_FSSETXATTR already, elsewhere).
The xfsctl wrapper is just to give some tools platform independence -
on IRIX (shares xfs_io code) some of the syscalls take paths, but on
Linux only file descriptors are used.

cheers.
