I feel like I need a script that given a sha, tells me what LTS
branches the patch is in or not. I have this to tell me "when (what's
the first tag that contains this commit)" a patch first landed:
function first_tag () {
tag=$1
git describe --contains "$tag" | sed 's/~.*//'
}
So say a patch landed in 4.15-rc1; and I want to backport to 4.9 and
4.14 (but it's already been backported to 4.14). Does anyone have a
script to check this quickly? The process for seeing which LTS
contains a commit or not still is very manual. I guess backports that
require modification probably complicate the search further. Just
asking, in case this is already a solved problem.
