[Qemu-devel] [PATCH v3 0/7] Misc improvements to crypto block driver

[Daniel P. Berrange]

This is a followup to

  v1: https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg00781.html
  v2: https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg06464.html

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
