[PATCH v2 00/10] makedumpfile: parallel processing

[Zhou Wenjian]

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.

  Add filter_data_buffer_parallel
  Add write_kdump_pages_parallel to allow parallel process
  Initial and free data used for parallel process
  Make makedumpfile available to read and compress pages parallelly
  Add usage and manual about multiple threads process
