Right? > Sorry, I'm a novice about this. Thanks. Sure, here is some information: https://www.kernel.org/doc/html/v4.10/process/stable-kernel-rules.html Applicable patches should be moved to the beginning of the series. Add "Cc: stable@xxxxxxxxxxxxxxx" similar to "Fixes:" to the respective patches. In the ideal case, indicate the applicable earliest stable release where it applies. E.g., take a look at (random commit) commit 20b329129009caf1c646152abe09b697227e1c37 Author: Bob Peterson <rpeterso@xxxxxxxxxx> Date: Wed Nov 18 08:54:31 2020 -0500 gfs2: Fix regression in freeze_go_sync ... Fixes: 541656d3a513 ("gfs2: freeze should work on read-only mounts") Cc: stable@xxxxxxxxxxxxxxx # v5.8+ ... Consequently, actually cc when sending out these patches (e.g., let "git send-email" do it automatically). -- Thanks, David / dhildenb
