Nice x 2, thanks again. More comments: @@ identifier f,i2,i1; struct i1 e1; expression e2; local idexpression x; position r.p; @@ ( -x = strlcpy +stracpy (e1.f, e2 - , i2 )@p; ... when != x Just for completeness and correctness, as I at least don't find an existing use: Perhaps this "x =" should also include += and + and the various other operators that are possible or does SmPL grammar already do that? Also, it might be nice to include the trivial conversion with sizeof(e1) and ARRAY_SIZE(e1) so a single script could be run over the kernel. I'll see about adding that and try it myself so an automated conversion should be possible.
