Hi All,

I am using the _IOWR macro in a piece of code. Although my structure
gets copied to the kernel ok (the states etc are preserved), if I
write back to that structure, the changes are not seen in user space.
Is there a known bug with this macro for 6.2 and is it fixed in a
later release?

Best Regards,
