[Qemu-block] [PATCH v6 0/8] qcow2: encryption threads

[Vladimir Sementsov-Ogievskiy]

v6:
 - Rebase on master, so 02 changed to reflect changes in
   qcow2_compress(), keep r-b.
 - Rewrite 06 to even simpler locking [Max], drop r-b
   Drop following
   "qcow2: qcow2_co_preadv: skip using hd_qiov when possible", I'll do
   it in my other coming soon series, and it is actually unrelated to
   current.
 - Drop controversial perf test, hope I'll return to this topic, but not
   in context of these series.
 - Add Max's r-b's to all here, except 06

Vladimir Sementsov-Ogievskiy (8):
  qcow2.h: add missing include
  qcow2: add separate file for threaded data processing functions
  qcow2-threads: use thread_pool_submit_co
  qcow2-threads: qcow2_co_do_compress: protect queuing by mutex
  qcow2-threads: split out generic path
  qcow2: qcow2_co_preadv: improve locking
  qcow2: bdrv_co_pwritev: move encryption code out of the lock
  qcow2: do encryption in threads
