Description

When creating a sub-directory under the directory with default LMV stripeEA, client needs to cache the default stripeEA on the client side, otherwise client might send the create request to the wrong MDT. So ll_getxattr_common should not check security in this case, otherwise only admin will be able to create new dir under such directory.
