Hi

I have compiled btrfs into the kernel instead of building as module.
Then I create a btrfs filesystem on a partition and try to mount it and
I get the following error.

# mkfs.btrfs /dev/sda1
fs created label (null) on /dev/sda1
        nodesize 4096 leafsize 4096 sectorsize 4096 size 4.88GB
Btrfs v0.16-8-g09ab036

# mount -t btrfs /dev/sda1 /mnt/sda1/
mount: unknown filesystem type 'btrfs'

If I perform the above steps with btrfs built as a module I don't get
any error.

Is this a known issue or am I doing something wrong?
