Description

sanity 102k of Lustre testset failed because setfattr retruns EINVAL in the SPARC machine.
This error occurs because lov magic number is mismatched on MDS.

This problem is that struct lov_user_md is accessed directly in mdc_setattr_pack
struct lov_user_md should be accessed by little endian.

Client log is as follows:
