Berrange (6):\n block: use 1 MB bounce buffers for crypto instead of 16KB\n crypto: expose encryption sector size in APIs\n block: fix data type casting for crypto payload offset\n block: convert crypto driver to bdrv_co_preadv|pwritev\n block: convert qcrypto_block_encrypt|decrypt to take bytes offset\n block: support passthrough of BDRV_REQ_FUA in crypto driver\n\n block/crypto.c | 130 ++++++++++++++++++++++++++-----------------------\n block/qcow.c | 11 +++--\n block/qcow2-cluster.c | 8 ++-\n block/qcow2.c | 4 +-\n crypto/block-luks.c | 18 ++++---\n crypto/block-qcow.c | 13 +++--\n crypto/block.c | 26 +++++++---\n crypto/blockpriv.h | 5 +-\n include/crypto/block.h | 29 ++++++++---\n 9 files changed, 148 insertions(+), 96 deletions(-)"}
