Josef Bacik 96f1bb5777 Btrfs: do not overcommit if we don't have enough space for global rsv ... Because of how little we allocate chunks now we can get really tight on metadata space before we will allocate a new chunk. This resulted in being unable to add device extents when allocating a new metadata chunk as we did not have enough space. This is because we were allowed to overcommit too much metadata without actually making sure we had enough space to make allocations. The idea behind overcommit is that we are allowed to say "sure you can have that reservation" when most of the free space is occupied by reservations, not actual allocations. But in this case where a majority of the total space is in use by actual allocations we can screw ourselves by not being able to make real allocations when it matters. So make sure we have enough real space for our global reserve, and if not then don't allow overcommitting.
