Namely, copy_siginfo_to_user() will nullify the extra SI_EXPANSION_SIZE bytes + 2*sizeof(__ARCH_SI_CLOCK_T) from _sigchld (waitid doesn't report utime/stime in siginfo). Looks correct... even the compat case, but please double-check copy_siginfo_to_user32/siginfo_layout. Looks like both SIL_KILL and SIL_CHLD cases are fine in that this patch can't add other user-visible changes, but I could easily miss something. > In case > anyone relies on the old behavior we can just revert we won't need to rever the whole patch, we can just replace copy_siginfo_to_user() with copy_to_user(offsetof(si_utime)). I see you are going to update the changelog and resend, feel free to add my reviewed-by. Oleg.
