xfs: fix over-copying of getbmap parameters from userspace [ Upstream commit be6324c00c4d1e0e665f03ed1fc18863a88da119 ] In xfs_ioc_getbmap, we should only copy the fields of struct getbmap from userspace, or else we end up copying random stack contents into the kernel. struct getbmap is a strict subset of getbmapx, so a partial structure copy should work fine.
