Thanks, Bjorn. I added in /root/.gitconfig ... [core] abbrev = 12 [pretty] fixes = Fixes: %h (\"%s\") ... Still, "git log" shows more than 12 digits, like: commit 0a528ee9a52007984fa60b0c4ef1f39fdf5edf8d Author: Tariq Toukan <tariqt@mellanox.com> Date: Wed Jun 7 16:26:15 2017 +0300 IB/mlx4: Bump driver version Does it work for you ?

Hi, I want to send a patch to LKML fixing something wrong which was caused by other patch.
Form what I understand, it is a good practice to mention the commit title and the commit ID.
A commit ID is very long. My question is: when mentioning in my commit log the patch that caused the problem, what is the minimum commit id length which I should use when presenting the patch that caused the problem ? is such commit length is documented anywhere ?
12
It's mentioned here and there. One place is the .git/config example in section "2) Describe your changes" in Documentation/process/submitting-patches.rst :
The following ``git config`` settings can be used to add a pretty format for outputting the above style in the ``git log`` or ``git show`` commands::
[core] abbrev = 12 [pretty] fixes = Fixes: %h (\"%s\")
(BTW, using the "Fixes" tag might be appropriate for your patch)
Or see for example: https://public-inbox.org/git/CA+55aFy0_pwtFOYS1Tmnxipw9ZkRNCQHmoYyegO00pjMiZ...
