commit 12cfc1983fa1521d6da94ad488145182cf97db2c

    cluster/ec: Improve performance with xattrop update
    
    Existing EC code updates the xattr on the subvolume
    in a sequential pattern resulting in very poor performance.
    
    With this fix EC now updates the xattr on the subvolume
    in parallel which improves the xattr update performance.
