[Qemu-devel] [PATCH v3 22/44] block: Kill blk_write(), blk_read() |
Date: |
Fri, 22 Apr 2016 17:40:30 -0600 |
Now that there are no remaining clients, we can drop these
functions, to ensure that all future users get the byte-based
interfaces. Sadly, there are still remaining sector-based
interfaces, such as blk_aio_writev; those will have to wait
for another day.
