From 8e3072a23ff8cf69b3e654a7cd64eae04f06a0e6 Mon Sep 17 00:00:00 2001 From: Josh Triplett Date: Thu, 3 Apr 2014 14:48:30 -0700 Subject: [PATCH] SubmittingPatches: document the use of git Most of the mechanical portions of SubmittingPatches exist to help patch submitters replicate the output of git. Mention this explicitly, both as a reminder that git will help with this process, and as signposting to let git users know what they can safely skip.
