[Qemu-devel] [PULL 08/32] dump: add support for lzo/snappy |
Date: |

From: qiaonuohan <address@hidden>
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
