[Libguestfs] [PATCH libnbd v3 0/3] copy: Use preferred block size for copying
v2 was:
https://listman.redhat.com/archives/libguestfs/2022-June/029321.html
v3:
- adds a test
- force sparseness detection size to be at least as large as the
target preferred size (otherwise you end up creating sub-requests
which are smaller than the preferred size)
Rich.
