Nope. I download the 'raw' patch [0] (assumed to be in mbox format?), then apply it via 'git am'. This workflow should preserve such patch metadata like commit description, Author's name/date, etc. > To get kernel patches and apply them easily, use the b4 tool available at: > > git://git.kernel.org/pub/scm/utils/b4/b4.git Thanks for sharing. This reminds me of patchwork/pwclient. I've reapplied the patches using 'b4' and Author's Date of the stable commits is still altered compared to the vanilla/mainline commits. For example: - Author's date of vanilla [2]: 2023-08-13 12:34:08 +0100 - Author's date of stable [1]: 2024-01-25 11:59:35 +0000 This likely means that the Author's date is amended during porting/cherry-picking. Of course, this is not a major issue, but some of us may assume that most of patch metadata (including Author's date) is preserved on backporting (as best practice). PS: We can likely skip it, since a number of other patches seem to alter the Author's date on 5.15 stable tree (~600 out of 21k+ commits).
