-Subject: [patch 4/4]#3 Remove redundant lp->siginfo
-
-Hi,
-
-this is a simplification which should not affect GDB behavior.  As linux-nat
-now stops on each received signal without any reordering of them then
-PTRACE_GETSIGINFO is enough to access siginfo, without any need to copy it in
-advance.
-
-
-Thanks,
-Jan

-       * linux-nat.c (resume_callback) <lp->stopped && lp->status == 0>
-       (linux_nat_resume): Remove LP->SIGINFO clearing.
-       (save_siginfo): Remove.
-       (stop_wait_callback) <WSTOPSIG (status) != SIGSTOP>
-       (linux_nat_filter_event) <linux_nat_status_is_event (status)>: Remove
-       the save_siginfo call.
-       (resume_stopped_resumed_lwps): Remove LP->SIGINFO clearing.
-       (linux_nat_set_siginfo_fixup): Use PTRACE_GETSIGINFO.
-       * linux-nat.h (struct lwp_info) <siginfo>: Remove.
