Subject: [PATCH v2 2/2] xfs/068: Verify actual file count instead of reported file count
Date: Sun, 27 Jan 2019 09:50:57 +0200	[thread overview]
Message-ID: <20190127075057.25254-2-amir73il@gmail.com> (raw)
In-Reply-To: <20190127075057.25254-1-amir73il@gmail.com>

This test has the number of files/dirs created by xfsrestore hardcoded
in golden output.

When fsstress is added new ops, the number of files/dirs created with
the same random seed changes and this regularly breaks this test,
so when new fsstress ops are added they should be either added to the
dump test blacklist or golden output of this test needs to be ammended
to reflect the change.

The golden output includes only the file count reported by xfsrestore
and test does not even verify that this is the correct file count.
Instead, leave the golden output nuetral and explicitly verify that
file count before and after the test are the same.

With this change, the test becomes agnostic to fsstress ops and we
could also stop blacklisting clone/dedup/copy ops if we want.
