Question about XFS as a module

[Frédéric L. W. Meunier <0@xxxxxxxxxxxxxx>]

Hi. From http://linux-xfs.sgi.com/projects/xfs/faq.html :

Q: Mounting the XFS filesystem does not work - what is wrong?

   If you get something like:
    mount: /dev/hda5 has wrong major or minor number

you either don't have XFS compiled into the kernel (or you
forgot to load the modules) or you did not use the "-t xfs"
option on mount or the "xfs" option in /etc/fstab.

My question is if I can use XFS without rebooting, only building
the module, or I also need to make bzImage ?
