Hi, I would like to improve the following coccinelle script: @@ expression a, fmt; expression list var_args; @@ - DBG_871X_LEVEL(a, fmt, var_args); + printk(fmt, var_args); I would replace the DBG_871X_LEVEL macro with printk, but I can't find a way to add KERN_* constant prefix to the fmt argument in the + code line. If i try this @@ expression a, fmt; expression list var_args; @@ - DBG_871X_LEVEL(a, fmt, var_args); + printk(KERN_DEBUG fmt, var_args); plus: parse error: File "../test.cocci", line 94, column 20, charpos = 1171 around = 'fmt', whole content = + printk(KERN_DEBUG fmt, var_args); how could I do this? thank you in advance, fabio
