Hi Changhuang,
Have you checked that these structs have the same layout for 32 and 64 architectures?
pahole is a useful tool for that.
I.e., if the kernel is 64 bit but userspace is compiled for 32 bit, then these structs
should still have the same layout.
It probably is fine, checking it with pahole is a good idea.
