+Subject: [PATCH] tuna: Fix string syntax warnings with raw strings
+
+tuna save <filename> allows you to save your kthreads tunables to
+a file to be used by rtctl. There were several backslashes that produce
+an error that pylint and Python (at least 3.12) gives a SyntaxWarning:
+invalid escape sequence
+
+Switch the strings written to the file with raw strings to resolve the
+warning for this section of the code.
+
+Tested by comparing the diffs of the files.
