Message-ID: <202202281042.733E768F@keescook> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Precedence: bulk List-ID: X-Mailing-List: linux-next@vger.kernel.org Hi! I was curious if it might be possible to emit the commit date along with the tree/SHA1 map in Next/SHA1s? That would let people trivially scan the file for relative age of trees, etc. -Kees -- Kees Cook
