tools/workspace/vtk_internal/patches/upstream/io_import_errors.patch line 1 at r1 (raw file):
nit The verb "restore" here doesn't make sense in context. There is no information provided about what is being restored, or from where. The original comment in #21090 was also more descriptive -- this is a nested loader.

So maybe something like this for the patch description (with better line wrapping):

[vtk] Partially revert upstream commit de160283

Upstream deleted important error handling that TRI added, and
it should be put back. Until that happens, we can unrevert the
deletion using this patch file.

When this patch is upstreamed again next time, the VTK team should
be sure to also add a unit test so that it doesn't get reverted again.

Original description of the fix that got reverted: be sure to forward
warnings and errors from the loader that's nested inside the
importer back to the importer proper.
