It was not caused by my bad patch. Without my patch, but with your revert instead I just got a crash (this time, I enabled lots of debugging options in the kernel, including KASAN) - it's the same crash as in the post I linked in my previous email:

------------[ cut here ]------------ WARNING: CPU: 13 PID: 3621 at fs/ceph/caps.c:3386 ceph_put_wrbuffer_cap_refs+0x416/0x500

Is that "WARN_ON_ONCE(ci->i_auth_cap);" for you?
