Hi, Here are steps of what I am doing: First, I created two commits to a demo project. when I use command: git format-patch --cover-letter -1 cat 0000-cover-letter.patch >From 2e62ef46d5627319c4cb11be81079e3364fca40c Mon Sep 17 00:00:00 2001 From: FanJun Kong <bh1scw@xxxxxxxxx> Date: Sun, 24 Apr 2022 14:31:45 +0800 Subject: [PATCH 0/1] *** SUBJECT HERE *** *** BLURB HERE *** FanJun Kong (1): Second commit. 1.c | 4 ++++ 1 file changed, 4 insertions(+) -- 2.32.0 (Apple Git-132) ok, you can see the cover letter has diffstat, just above "--". Then I change command to: git format-patch --cover-letter -2 cat 0000-cover-letter.patch >From 2e62ef46d5627319c4cb11be81079e3364fca40c Mon Sep 17 00:00:00 2001 From: FanJun Kong <bh1scw@xxxxxxxxx> Date: Sun, 24 Apr 2022 14:34:48 +0800 Subject: [PATCH 0/2] *** SUBJECT HERE *** *** BLURB HERE *** FanJun Kong (2): First commit. Second commit. -- 2.32.0 (Apple Git-132) Comparing with last command, I just want to get 2 patches, but this time the diffstat is missing. I am not sure if this is a bug or I miss some options. I googled this issue, but not got too much. Thanks for your time. Fanjun Kong
