[ceph-users] rbd online sparsify image

Hello community experts, I would like to know the status of rbd image sparsify. From the website, it should be added at Nautilus ( https://docs.ceph.com/en/latest/releases/nautilus/ from pr (26226 <https://github.com/ceph/ceph/pull/26226>,) ) but on mimic it is related again https://docs.ceph.com/en/latest/releases/octopus/) Is it still the same commit? or is there any update/bug fixes that is not backported to 14.x? I am also curious why it is named re-sparsify in the pr title? Thank you very much for the help. -- Best Regards, Jiatong Shen
