[ceph-users] Cephfs kernel client bug report

Hi. I'm new here.  I have been playing with ceph for a few years (nothing dramatic, just using it in my proxmox cluster to store VM images and host a cephfs with a lot of shared files).  I think I found a bug in the cephfs client in the Linux kernel.  Listing snapshots (ls .snap) in a lot of directories quickly causes a kernel panic.  I tried to create an account on the bug tracker at tracker.ceph.com a week ago, but still can't log in there.  Do I put details here, or report somewhere else?  What's the next step I should take? Thanks, Alain
