This could be more explicit about the details of the change. Ideally we should point to an actual test program whose results are changed by fixing the kernel. I think the best thing to say is that previously using purely PTRACE_SINGLESTEP without regard to what the user instructions were could sometimes swallow a provided signal, whereas now it treats the syscall instruction like any other user instruction.
