Requests have to be unlinked from both osd->o_requests (normal requests) and osd->o_linger_requests (linger requests) lists when clearing req->r_osd. Otherwise __unregister_linger_request() gets confused and we trip over a !list_empty(&osd->o_linger_requests) assert in __remove_osd(). MON=1 OSD=1: # cat remove-osd.sh #!/bin/bash rbd create --size 1 test DEV=$(rbd map test) ceph osd out 0 sleep 3 rbd map dne/dne # obtain a new osdmap as a side effect rbd unmap $DEV & # will block sleep 3 ceph osd in 0 Signed-off-by:
