I cloned libnfs (fb6f315257a8752c3a8b96a71261a5613a6f2069) and found it
does not install nfsc/libnfs-raw-mount.h. Any idea what's going on
here, should the include be dropped from your patch?
qemu_opts_create_nofail() no longer exists (see
87ea75d5e135c0527c6a9dbac4317913409f28c7), the following is needed to
make it compile:
- opts = qemu_opts_create_nofail(&runtime_opts);
+ opts = qemu_opts_create(&runtime_opts, NULL, 0, &error_abort);
Please send a final cleaned up series.
Thanks,
Stefan
