This is described in Documentation/SubmittingPatches as If you want to reference a previous commit in the history of a stable branch, use the format "abbreviated hash (subject, date)", like this: .... Commit f86a374 (pack-bitmap.c: fix a memleak, 2015-03-30) noticed that ... .... Since this format is so commonly used, standardize it as a pretty format. The tests that are implemented essentially show that the format-string does not change in response to various log options. This is useful because, for future developers, it shows that we've considered the limitations of the "canned format-string" approach and we are fine with them.
