v1-0001-Fix-incorrect-documentation-for-test_custom_stats.patch (application/octet-stream)

31280d96a6 updated the wrong section of the documentation to
reference the new test_custom_stats module. The reference should
have been under  "Custom Cumulative Statistics" section instead of
the "Injection Points" section.

Attached is the fix.
