Subject: Re: [PATCH V3 13/17] MdeModulePkg/PeiDxeDebugLibReportStatusCode: Add new APIs
Date: Thu, 21 Mar 2019 06:57:48 +0000 [thread overview]
Message-ID: <4A89E2EF3DFEDB4C8BFDE51014F606A14E408772@SHSMSX104.ccr.corp.intel.com> (raw)
In-Reply-To: <20190319152549.16104-14-zhichao.gao@intel.com>
Zhichao:
Why do below change? Seemly, this change is not related to add new APIs. In fact, current log is added as the purpose by commit 137ed15511e2045a7333e33ae7f1e873ce1961dd.
if (TotalSize > sizeof (Buffer)) {
TotalSize = sizeof (Buffer); ==> return;
}
Thanks
Liming
