Hi all.

These series are preliminary step before moving encryption code in
qcow2 to the threads. The first attempt of doing it is on list
([PATCH 00/11] qcow2: encryption threads : 
 https://lists.gnu.org/archive/html/qemu-block/2018-11/msg00729.html)
But it's approach with multiplying the whole QCryptoBlock per thread
was rejected. So, here is a solution to maintain multitasking inside
QCryptoBlock.

Patch 01 may be considered as 3.1-rc4 material, others are ofcourse
for 4.0.

Vladimir Sementsov-Ogievskiy (5):
  crypto/block-luks: fix memory leak in qcrypto_block_luks_create
  crypto/block: refactor qcrypto_block_*crypt_helper functions
  crypto/block: rename qcrypto_block_*crypt_helper
  crypto/block: introduce qcrypto_block_*crypt_helper functions
  crypto: support multiple threads accessing one QCryptoBlock
