-----------------------------------
[~umamaheswararao] Thanks for your comments.

instead of accessing name system internals all around, how about block manager
talk to name system?
{quote}
I have two concerns about this point:
* Xattr is supposed to work on Inode, not block. Is it good to remove in block
manager?
* {{BlockStorageMovementAttemptedItems}} is instanced before block manager, if
it holds block manager, the value of block manager will always be a null.
Currently I don't have an idea about how to get the instanced block manager
while removing the xattr.
