+Subject: [PATCH hurd 2/6] libpager: use libports notification functions
+
+Now that we do not use sequence numbers anymore, we can simply use
+libports notification server functions.
+
+* libpager/Makefile (SRCS): Drop `no-senders.c', and `notify-stubs.c'.
+(OBJS): Drop `notifyServer.o'.
+* libpager/demuxer.c (pager_demuxer): Use libports server functions.
+* libpager/mig-mutate.h: Drop all notification mutators.
+* libpager/no-senders.c: Remove file.
+* libpager/notify-stubs.c: Likewise.

+Subject: [PATCH hurd 3/6] Replace `bzero' with `memset'
+
+For reference, this patch was created using the following semantic
+patch, and then manually applying the change in all functions
+containing nested functions, as those are not supported by Coccinelle.

+* libports/manage-one-thread.c (ports_manage_port_operations_one_thread):
+Likewise.
+* libports/destroy-right.c (ports_destroy_right): Defer the
