Sure Lukas.
I have a doubt though, Can't we use a single expression separated by
"|" here, instead of multiple lines? i.e.,
$x =~
s/__packed|__aligned|____cacheline_aligned_in_smp|____cacheline_aligned|__attribute__\s*\(\([a-z0-9,_\s\(\)]*\)\)\s*//;
Probably we could do something similar for dump_function, i.e.,
- $prototype =~ s/^static +//;
- $prototype =~ s/^extern +//;
- $prototype =~ s/^asmlinkage +//;
- $prototype =~ s/^inline +//;
- $prototype =~ s/^__inline__ +//;
- $prototype =~ s/^__inline +//;
- $prototype =~ s/^__always_inline +//;
- $prototype =~ s/^noinline +//;
+ $prototype =~
s/^(?:static|extern|asmlinkage|__?inline__?|__always_inline|noinline) +//;
And so on for other regexps.
What do you think?
Thanks
Aditya
