From 883aafe6bde1e6b45653c5b5b407877fb54a0a69 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Sat, 22 Mar 2014 03:31:02 +0100 Subject: [PATCH 11/30] dump: add support for lzo/snappy RH-Author: Laszlo Ersek Message-id: <1395459071-19118-11-git-send-email-lersek@redhat.com> Patchwork-id: 58221 O-Subject: [RHEL-6.6 qemu-kvm PATCH 10/19] dump: add support for lzo/snappy Bugzilla: 1035162 RH-Acked-by: Paolo Bonzini RH-Acked-by: Dr. David Alan Gilbert (git) RH-Acked-by: Luiz Capitulino From: qiaonuohan kdump-compressed format supports three compression format, zlib/lzo/snappy. Currently, only zlib is available. This patch is used to support lzo/snappy. '--enable-lzo/--enable-snappy' is needed to be specified with configure to make lzo/snappy available for qemu Signed-off-by: Qiao Nuohan Reviewed-by: Laszlo Ersek Signed-off-by: Luiz Capitulino (cherry picked from commit 607dacd0a082a4ea73a7a16a1c70406f37ebacdb) Conflicts: configure RHEL-6 note: this is actually a manual reimplementation disguised as conflict resolution, but I kept the cherry-picked line to satisfy Jeff's git-backport-diff script.
