Description Jeff Layton 2018-08-13 13:56:04 UTC 
If you forcibly unmount a libcephfs filesystem and later call ceph_ll_close on a Fh that you got before the unmount, the program can crash due to bad pointer dereferences in some log output.

Patch 3c94f23d3b10928615a0f1381eb758006db84b13 in the upstream ceph userland tree should fix this (at least for ceph_ll_close).
