This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Step 1 in trying to slowly rip the zdb functions out of zdb.c to allow people to play with more flexible things to leverage zdb's functionality. No promises on any functions or structs being stable, now or probably in general unless someone builds a more polished abstraction, the goal at the moment is to slowly untangle the global state usage in zdb... Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Rich Ercolani <rincebrain@gmail.com> Closes #15804
