Subject: [Qemu-devel] [PATCH 0/5] qcow2: Implement .bdrv_co_preadv/pwritev
Date: Fri, 3 Jun 2016 19:21:13 +0200 [thread overview]
Message-ID: <1464974478-23598-1-git-send-email-kwolf@redhat.com> (raw)
This series converts qcow2 to the byte-based I/O interfaces. This simplifies
the code by removing many unit conversions, and in the unlikely case of actual
unaligned requests, it even makes the driver work more efficiently by avoiding
read-modify-write.
Kevin Wolf (5):
qcow2: Work with bytes in qcow2_get_cluster_offset()
qcow2: Implement .bdrv_co_preadv()
qcow2: Make copy_sectors() byte based
qcow2: Use bytes instead of sectors for QCowL2Meta
qcow2: Implement .bdrv_co_pwritev
