[PATCH libnbd 0/8] nbdcopy: Adaptive queue size
by Nir Soffer
This series add adaptive queue size feature, which gives great
performance improvmemnt on my laptop, but less exciting results on a
real server. When qemu-nbd will support MULTI-CON for writes, this
should become more interesting.
To implement this I added a worker struct for keeping worker state, and
cleaned up the completion flow and other stuff. I think these cleanups
are a good idea even if we do not add adaptive queue size.
Nir Soffer (8):
copy: Remove wrong references to holes
copy: Rename copy_subcommand to create_subcommand
copy: Extract create_command and create_buffer helpers
copy: Separate finishing a command from freeing it
copy: Introduce worker struct
copy: Keep worker pointer in command
copy: Track worker queue size
copy: Adaptive queue size
