Subject: [PATCH v2 4/7] bug: Enable DEBUG_CREDENTIALS under BUG_ON_DATA_CORRUPTION
Date: Tue,  4 Apr 2017 15:12:15 -0700	[thread overview]
Message-ID: <1491343938-75336-5-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1491343938-75336-1-git-send-email-keescook@chromium.org>

Since CONFIG_DEBUG_CREDENTIALS already handles reporting and issuing a
BUG when it encounters corruption, add this to the list of corruption
test CONFIGs that are enabled under CONFIG_BUG_ON_DATA_CORRUPTION.
