Yes, it is. Thanks!

Firstly, why bother? And I will talk why this tag should be kept, as a stable tree maintainer. At the beginning, when people are not used to add "cc: stable" tag, I used to pick bug fix commits from master by something like: list all bug fixing patches and pick those that appliable to previous release. Later, kudos to Thomas, who wrote an handy script (git-log-fixes.sh) to do both, it indeeded make my life much easier. But it's still not enough. It lists a lot of patches (206 fix patches, while 728 in total: the ratio is near 30%): $ devtools/git-log-fixes.sh v16.07..v16.11 | wc -l 206 $ git rev-list v16.07..v16.11 | wc -l 728 Thus I dropped few of them, manually, resulting to 130 (still looks like a big number to me): $ git rev-list v16.07..v16.07.2 | wc -l 130 The policy I would expect is, leave this tag as it is, I then will apply all of them to a stable branch: I will no longer do the picking job. Instead, I may just need handle those can't apply cleanly and ask the author to do backport. It would be do-able now, as I saw a lot of people are getting used to add such tag. And even not, I saw those kind committers do that for them. Besides, if there is already an explicit way, why should we stick on the implicit way? --yliu > this will generate warnings when run against existing history. > > I don't know what can be done for this. > > Or should we keep CC: tags in commit log perhaps? > > >
