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:

Josef Bacik (10) commits (+517/-160):
    Btrfs: make set/get functions for the super compat_ro flags use compat_ro (+1/-1)
    Btrfs: change the ordered tree to use a spinlock instead of a mutex (+19/-19)
    Btrfs: add ioctl and incompat flag to set the default mount subvol (+80/-1)
    Btrfs: cache the extent state everywhere we possibly can V2 (+148/-90)
    Btrfs: make subvolid=0 mount the original default root (+9/-3)
    Btrfs: make df be a little bit more understandable (+26/-3)
    Btrfs: cache extent state in find_delalloc_range (+8/-3)
    Btrfs: cache ordered extent when completing io (+10/-5)
    Btrfs: change how we mount subvolumes (+158/-34)
    Btrfs: add a "df" ioctl for btrfs (+58/-1)

    Btrfs: don't look at bio flags after submit_bio (+3/-3)
    Btrfs: be more selective in the defrag ioctl (+140/-10)
    Btrfs: add search and inode lookup ioctls (+299/-16)
