The r_req_lru_item list node moves between several lists, and that cycle is not directly related (and does not begin) with __register_request(). Initialize it in the request constructor, not __register_request(). This fixes later badness (below) when OSDs restart underneath an rbd mount. Crashes we've seen due to this include: [ 213.974288] kernel BUG at net/ceph/messenger.c:2193! and [ 144.035274] BUG: unable to handle kernel NULL pointer dereference at 0000000000000048 [ 144.035278] IP: [<ffffffffa036c053>] con_work+0x1463/0x2ce0 [libceph] Signed-off-by: Sage Weil <sage@newdream.net> |
