linuxolator: proc/filesystems implementation

[Scot Hetzel]

Linux has a file in the procfs that shows all the loaded filesystem modules.

I have implemented the function that fills this file using the linprocfs module.

What the function does is look for specific kernel modules using
module_lookupbyname to create an entry in the proc/filesystems file:

# cat /compat/linux/proc/filesystems
            cd9660
nodev   devfs
nodev   bsdprocfs
            mfs
            msdosfs
            nfs
            nfs4
nodev   procfs
nodev   sysfs
            ufs
# kldload smbfs
# cat /compat/linux/proc/filesystems
            cd9660
nodev   devfs
nodev   bsdprocfs
            mfs
            msdosfs
            nfs
            nfs4
nodev   procfs
            smbfs
nodev   sysfs
            ufs

Unloading a filesystem kernel module will remove the entry from
proc/filesystems.
