I've updated the master tree with 3 small fixes.  Thanks to Sage for
sending along a one liner for a bad cast in the searching ioctl, really
not sure why my gcc isn't giving the same warnings his was.

I fixed the new space info ioctl to avoid scheduling in a
rcu_read_lock.  Sage also turned u64 to __u64 in the space_info ioctl
args struct.

Here is the corrected shortlog:

    Btrfs: make set/get functions for the super compat_ro flags use compat_ro (+1/-1)

    Btrfs: cache the extent state everywhere we possibly can V2 (+148/-90)
    Btrfs: make subvolid=0 mount the original default root (+9/-3)
