First of all we would have to consider commit 1c8924eb106c1ac755d5d35ce9b3ff42e89e2511 as well since you make a use of the function introduced in that commit. Also it's quite big change to be pushed to stable. However I think that the warning is actually mostly harmless since we have 27dd43854227bb0e6ab70129bd21b60d396db2e7 ext4: introduce reserved space so If I am not missing something, then chances that we'll end up with no space to allocate metadata blocks from are very very low.
