Author: bdrewery Date: Thu Jul 23 23:29:50 2020 New Revision: 363463 URL: https://svnweb.freebsd.org/changeset/base/363463 Log: Limit gmirror failpoint tests to the test worker This avoids injecting errors into the test system's mirrors. gnop seems like a good solution here but it injects errors at the wrong place vs where these tests expect and does not support a 'max global count' like the failpoints do with 'n*' syntax.
