Subject: scripts/kernel-doc: Escape all literal braces in regexes
|
||||
Bug-Debian: https://bugs.debian.org/905116

||||
Forwarded: https://marc.info/?l=linux-doc&m=153348608531181&w=2
|
||||
|
||||
Braces are usually metacharacters in regexes, used to specify a
|
||||
number of repetitions or as part of an escape sequence. If this
|
||||
interpretation is not possible then Perl currently treats them
|
||||
as literal characters.
|
||||
|
||||
Perl 5.28 has deprecated the literal interpretation of left braces,
|
||||
and Perl 5.32 will remove it (resulting in a fatal error).
|
||||
|
||||
Escape all left braces that are treated as literal characters. Also
|
||||
escape literal right braces, for consistency and to avoid confusing
|
||||
bracket-matching in text editors.
