The command-set filter dereferences req->ns,\nbut this handler never calls nvmet_req_find_ns(), so req->ns is always\nNULL (nvmet_req_init() resets it to NULL). As soon as an enabled\nnamespace with an NSID greater than the requested value exists,\nreq->ns->csi dereferences a NULL pointer and oopses.\n\nBesides the crash, the comparison is logically wrong: to filter the list\nby command set it must test the command set of the namespace being\niterated, not a single fixed value. Use the loop variable ns->csi."
