From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx> Subject: seq_file: convert seq_escape() to use seq_escape_str() Convert seq_escape() to use seq_escape_str() rather than open coding it. Note, for now we leave it as an exported symbol due to some old code that can't tolerate ctype.h being (indirectly) included.
