Hello Rafael,
Thank you very much for the patch, but looks like it is not correct. The
Userspace API header is supposed to be used by kernel and userspace, the
__packed macro is available in kernel only.
Interestingly there few places in include/uapi/ that use __packed macro, I'm
wondering if they are correct. Note that GCC just won't complain about
undefined qualifier, at least by default.
