This collection of patches first improves the performance of the crypto block driver and then does various cleanups to improve ongoing maint work. Changed in v3: - Support passthrough of BDRV_REQ_FUA (Eric) - Fix potential truncation of payload offset values (Eric) - Use encryption scheme sector size instead of BDRV_SECTOR_SIZE (Kevin) - Use QEMU_IS_ALIGNED where appropriate (Eric) - Remove unused 'sector_num' variable (Eric) - Fix whitespace alignment (Eric) - Fix math error in qcow conversion (Eric) Daniel P. Berrange (7): block: use 1 MB bounce buffers for crypto instead of 16KB crypto: expose encryption sector size in APIs block: fix data type casting for crypto payload offset block: don't use constant 512 as sector size in crypto driver block: convert crypto driver to bdrv_co_preadv|pwritev block: convert qcrypto_block_encrypt|decrypt to take bytes offset block: support passthrough of BDRV_REQ_FUA in crypto driver block/crypto.c | 134 +++++++++++++++++++++++++++---------------------- block/qcow.c | 7 ++- block/qcow2-cluster.c | 8 ++- block/qcow2.c | 4 +- crypto/block-luks.c | 18 ++++--- crypto/block-qcow.c | 13 +++-- crypto/block.c | 26 +++++++--- crypto/blockpriv.h | 5 +- include/crypto/block.h | 29 ++++++++--- 9 files changed, 150 insertions(+), 94 deletions(-) -- 2.13.5
