[GIT] 4.3.0 vs 4.3.0-forward - where to commit?

[ilya musayev]

Looks like few patches that i've backported to 4.3.0-forward have been 
dropped (dont see my commits). i am now under impression i should have 
commited to 4.3.0 branch.

Would someone please clarify the difference between the two and where to 
commit when i need to backport/cherry-pick a patch?

Thanks
