Re: py-libzfs build failure on current, zpool_search_import() missing

[Alexander Leidinger]

Quoting Ryan Moeller  (from Fri, 3 Feb 2023  
10:48:35 -0500):



The build still fails on -current as of end of Jan with "too few
argument to function call, expected 4, have 3" for zfs_iter_filesystems.

Is a patch for openzfs in -current missing? I haven't seen a commit to
-current in openzfs in the last 2 days.


The openzfs changes aren't that recent, but the py-libzfs port has
been out of date for a while. I'll spin up a new snapshot VM and fix
whatever is still broken.


I can confirm that the 20230207 version of py-libzfs builds (and  
works) on -current. Thanks!


Bye,
Alexander.
