FWIW, I use this shell alias to generate these references:

  gsr is aliased to `git --no-pager show -s --abbrev-commit --abbrev=12 --pretty=format:"%h (\"%s\")%n"'

  $ gsr fb51ccb
  fb51ccbf217c ("PCI: Rework config space blocking services")

Documentation/process/submitting-patches.rst mentions a 12-char (at
least) SHA-1 but the e21d2170f36 example shows a *20*-char SHA-1,
which seems excessive to me.

I personally skip the word "commit" because I figure it's pretty
obvious what it is, but it's fine either way.
