In theory, I think all of these require backporting, and each carries a = certain level of potential impact. >=20 > Ideally, split the series up into one series for 7.1-rcX+stable, = another > series for 7.2.rc1. Given that these issues have existed for a long time and the trigger frequency is very low, I suggest we take a more conservative timing. We can prioritize getting the series into 7.2-rc1 first. Once they have 'baked' in the mainline for a while without issues, we can then proceed with the backport to -stable (7.1.x). This avoids rushing risky changes into stable branches. Thanks, Muchun
