+Subject: [PATCH] [ArPow] Use --work-tree with git apply
+
+This makes things work better in a source-tarball build, where there may
+be a .git directory somewhere in our parent directories but it's for a
+different repo than vstest. In a situation like that a plain `git apply`
+will (silently!) ignore patches because they wont apply to the unrelated
+repository. That will (eventually) make the source-build fail.
+`--work-tree` makes git directly use the directory that we care about.
+
+See https://github.com/dotnet/source-build/issues/2445 for more details.
