We find some errors in the previous calculation of leading log QCD corrections to b --> s gamma decay, which include corrections from m(top) to M(W) in addition to corrections from M(W) to m(b). The inclusive decay rate is found to be enhanced more than previous calculations. At m(t) = 170 GeV, the running from m(top) to M(W) results in 13% enhancement, and for m(t) = 250 GeV, 16% enhancement is found.
