The zatm_t_hist structure is not used anywhere in the kernel, but is exported to user space. As we are trying to eliminate uses of time_t in the kernel for y2038 compatibility, the current definition triggers checking tools because it contains 'struct timeval'.
We can work around this by adding '#ifdef __KERNEL__'. I could not find out what the structure is actually used for, so this is the safe choice in case there is some user space tool that relies on the definition.
If we are sure that nothing in user space relies on the structure, we can instead remove the definition completely.
It was used by the ZATM_GETHIST ioctl which is long since gone in the kernel driver. You can just remove this.
Perfect, I've updated the patch accordingly, see follow-up mail
