Re: [PATCH v5 1/9] scatterlist: add sg_zeroout_area() helper

[Sagi Grimberg]

+       while ((offset < buflen) && sg_miter_next(&miter)) {
+               unsigned int len;
+
+               len = min(miter.length, buflen - offset);
+               memset(miter.addr, '\0', len);

Why '\0' and not 0?
