Re: [Libguestfs] [nbdkit PATCH v3 05/15] filters: Add blocksize filter

Testing is easy by reusing the log filter and observing that requests were rewritten as expected (well, with the slight complication that different versions of qemu-io vary in whether they obey the NBD spec of limiting themselves to 512-byte I/O if we don't advertise otherwise with NBD_OPT_GO, or in just directly handing us byte-based I/O anyway - so the test has to round to something even bigger to be sure it sees a difference).
