[dm-devel] 答复: Re: [PATCH] multipathd: fix issue in 'map $map getprstatus' reply

Hi Bart,

Thanks again.
I got it.

-       *len = 3;
-       asprintf(reply, "%d\n", mpp->prflag);
+       *len = asprintf(reply, "%d\n", mpp->prflag);
+       if (*len < 0)
+               return 1;

Hello Peng,

Please use the return value of asprintf() to compute *len instead of 
assigning a hard-coded constant to *len.

Thanks,

Bart.
