Subject: [Qemu-devel] [PATCH v2 0/4] block: improve luks driver perf & switch to byte APIs
Date: Thu, 31 Aug 2017 12:05:14 +0100 [thread overview]
Message-ID: <20170831110518.10741-1-berrange@redhat.com> (raw)
This series includes a previously posted patch that improves performance
of the luks crypto driver:
https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg00781.html
And then adds three patches that switch over to use byte based APIs for
I/O, rather than the legacy sector based APIs.
Daniel P. Berrange (4):
block: use 1 MB bounce buffers for crypto instead of 16KB
block: use BDRV_SECTOR_SIZE in crypto driver
block: convert crypto driver to bdrv_co_preadv|pwritev
block: convert qcrypto_block_encrypt|decrypt to take bytes offset
