>This patch set implements parallel processing by means of multiple threads.
>With this patch set, it is available to use multiple threads to read
>and compress pages. This parallel process will save time.
>This feature only supports creating dumpfile in kdump-compressed format from
>vmcore in kdump-compressed format or elf format. Currently, sadump and
> xen kdump are not supported.
