If we keep the "old way" than I have an additional question: Wouldn't a "git cherry-pick -Xsubtree=3Dsys/contrib/openzfs" from the=20 vendor branch be a better way to go than "git merge=20 -Xsubtree=3Dsys/contrib/openzfs"? Especially for stable/13, where I have=20 to "merge" in the whole new vendor/openzfs/zfs-2.1-release branch. mm On 12. 4. 2021 11:02, Ulrich Sp=C3=B6rlein wrote: > On Sun, 2021-04-11 at 01:03:30 +0200, Martin Matuska wrote: >> Thank you for your comments, Warner. >> >> What I would like to know is the timing - how much time do we need to >> resolve the issues.
