+Subject: [PATCH] kpatch-cc: fix stripping of source tree prefix
+
+To support building out-of-tree kernel modules, the source tree prefix
+is attempted to be stripped from change object file paths to make them
+relative. However, if the path is already relative, the change can
+strip a substring instead, resulting in build errors.
+
+Ensure just the prefix is stripped instead of any substring.
+
+Fixes: #1282
+Fixes: 51a8fad34ff3 ("Add support for building out-of-tree modules")
