Hi, Ben Hutchings reported in https://bugs.debian.org/1064035 a problem with the kernel-doc builds once 3080ea5553cc ("stddef: Introduce DECLARE_FLEX_ARRAY() helper") got applied in 5.10.210 (as prerequisite of another fix in 5.10.y): > The backport of commit 3080ea5553cc "stddef: Introduce > DECLARE_FLEX_ARRAY() helper" modified scripts/kernel-doc and > introduced a syntax error: > > Global symbol "$args" requires explicit package name (did you forget to declare "my $args"?) at ./scripts/kernel-doc line 1236. > Global symbol "$args" requires explicit package name (did you forget to declare "my $args"?) at ./scripts/kernel-doc line 1236. > Execution of ./scripts/kernel-doc aborted due to compilation errors. > > This doesn't stop the documentation build process, but causes the > documentation that should be extracted by kernel-doc to be missing > from linux-doc-5.10. > > We should be able to fix this by eithering backport commit > e86bdb24375a "scripts: kernel-doc: reduce repeated regex expressions > into variables" or replacing /$args/ with /([^,)]+)/. > > Ben. What would be prefered here from stable maintainers point of view? AFAICS e86bdb24375a ("scripts: kernel-doc: reduce repeated regex expressions into variables") won't apply cleanly and needs some refactoring. The alternative pointed out by Ben would be to replace the /$args/ with /([^,)]+)/. # 5.10.y specific regression #regzbot introduced: 443b16ee3d9ce0a3ece0e3526a5af883e5b16eaf #regzbot link: https://bugs.debian.org/1064035 Regards, Salvatore
