From: Hongchao Zhang <hongchao.zhang@intel.com>
For IMA (Integrity Measurement Architecture), there are two xattr "security.ima" and "security.evm" to protect the file to be modified accidentally or maliciously, the two xattr are not compatible with VBR, then disable it to workaround the problem currently and enable it when the conditions are ready.
