From 1f9d175ded89c7d1e3d3b76b32d107c565887e81 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Fri, 7 Nov 2014 17:17:51 +0100 Subject: [PATCH 04/41] dump: add argument to write_elfxx_notes Message-id: <1415380693-16593-5-git-send-email-lersek@redhat.com> Patchwork-id: 62190 O-Subject: [RHEL-7.1 qemu-kvm PATCH 04/26] dump: add argument to write_elfxx_notes Bugzilla: 1157798 RH-Acked-by: Stefan Hajnoczi RH-Acked-by: Luiz Capitulino RH-Acked-by: dgibson From: qiaonuohan write_elf32_notes/wirte_elf64_notes use fd_write_vmcore to write elf notes to vmcore. Adding parameter "WriteCoreDumpFunction f" makes it available to choose the method of writing elf notes Signed-off-by: Qiao Nuohan Reviewed-by: Laszlo Ersek Signed-off-by: Luiz Capitulino (cherry picked from commit 6a519918b3f666759e20bcd0bb88378f3e4ffb57) Signed-off-by: Miroslav Rezanina Conflicts: dump.c Conflicts are due to our not having upstream commit 182735ef ("cpu: Make first_cpu and next_cpu CPUState").
