Yes, upmap will work with 4.15. The Ceph kernel client is a completely independent implementation from the user space client, so you can't really map it to any specific features. It has some Luminous features but lacks others.

Hello ml,
I have been looking for an updated table like the one you can see here:
https://ceph.com/geen-categorie/feature-set-mismatch-error-on-ceph-kernel-client/
Case in point we would like to use upmap on our ceph cluster (currently
used mainly for CephFS) but `ceph feature` return:
"client": [
{
"features": "0x7010fb86aa42ada",
"release": "jewel",
"num": 69
},
]
despite the CephFS clients running with a fairly recent 4.15 kernel.
If anyone has any pointers they would be most welcome
Kind regards
Mattia
