Subject: seq_file: add seq_escape_str() as replica of string_escape_str()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=01f172db4290711f64ce7a258b2734a3f268033a;p=users%2Fjedix%2Flinux-maple.git

seq_file: add seq_escape_str() as replica of string_escape_str()

In some cases we want to escape characters from NULL-terminated strings.
Add seq_escape_str() as replica of string_escape_str() for that.
