If the procfile creation fails, then the kernel\nwill WARN when it tries to remove the entry later.\nFix nfsd_proc_stat_init() to return the same type of pointer as\nsvc_proc_register(), and fix up nfsd_net_init() to check that and fail\nthe nfsd_net construction if it occurs.\nsvc_proc_register() can fail if the dentry can't be allocated, or if an\nidentical dentry already exists. The second case is pretty unlikely in\nthe nfsd_net construction codepath, so if this happens, return -ENOMEM." ],
