[Qemu-block] [PATCH v3 0/5] crypto threads

[Vladimir Sementsov-Ogievskiy]

Hi all.

v3:
01: add r-b by Daniel and Alberto
02: Alberto r-b
    encrypt->encdec for generic
03: qcrypto_cipher_*crypt_helper->
    qcrypto_block_cipher_*crypt_helper
04: rebased on previous renamings
    Daniel r-b
05: use size_t
    improve comment about n_threads
    don't use ret in qcrypto_block_luks_create
    do qemu_mutex_init at the end of open/create
    do qemu_mutex_destroy in free
    fix comment for qcrypto_block_get_cipher

v2:
05: fix compilation of test-crypto-block (I am ashamed:(
    and change QCryptoBlock interface to be a bit more safe.

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.

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
