It is a straight-up bug fix for a 7.2 regression that's now affected several users. - It has two Tested-by tags on the thread. - hpa, the maintainer of the kernel side of this, confirmed on one of the various tributary threads that this approach is a correct one. - It doesn't introduce any new functionality. For your convenience, you can grab this out of lore here: https://lore.kernel.org/lkml/20221230220725.618763-1-Jason@zx2c4.com/ Or if you want to yolo it: curl https://lore.kernel.org/lkml/20221230220725.618763-1-Jason@zx2c4.com/raw | git am -s It's now sat silent on the mailing list for a while. So let's please get this committed and backported so that the bug reports stop coming in. Thanks, Jason
