Re: [Libguestfs] [nbdkit PATCH v2 6/6] multi-conn: Add knob to limit consistency emulation by export name

We can't enable the knob by default since many nbdkit plugins don't care about export name, but it is certainly more efficient to limit consistency to just clients visiting the same export. Thankfully, NBD_CMD_FLUSH does not take size and offset, and therefore is safe (although wasting CPU cycles) to use even when a different export has a different size. --- .../multi-conn/nbdkit-multi-conn-filter.pod | 29 +++++- tests/Makefile.am | 2 + filters/multi-conn/multi-conn.c | 31 ++++++- tests/test-multi-conn-name.sh | 88 +++++++++++++++++++ tests/test-multi-conn-plugin.sh | 63 ++++++++----- 5 files changed, 186 insertions(+), 27 deletions(-) create mode 100755 tests/test-multi-conn-name.sh
