Log:
  MFC r329508: MFV r324198: 8081 Compiler warnings in zdb
  
  illumos/illumos-gate@3f7978d02b206a6ebc5652c91aa9f42da6fbe00c
  https://github.com/illumos/illumos-gate/commit/3f7978d02b206a6ebc5652c91aa9f42da6fbe00c
  
  https://www.illumos.org/issues/8081
    zdb(8) is full of minor problems that generate compiler warnings. On FreeBSD,
    which uses -WError, the only way to build it is to disable all compiler
    warnings. This makes it much harder to detect newly introduced bugs. We should
    cleanup all the warnings.
