Vasily Averin 156c80d4e1 race of lockd inetaddr notifiers vs nlmsvc_rqst change ... [ Upstream commit 6b18dd1c03 ] lockd_inet[6]addr_event use nlmsvc_rqst without taken nlmsvc_mutex, nlmsvc_rqst can be changed during execution of notifiers and crash the host. Patch enables access to nlmsvc_rqst only when it was correctly initialized and delays its cleanup until notifiers are no longer in use. Note that nlmsvc_rqst can be temporally set to ERR_PTR, so the "if (nlmsvc_rqst)" check in notifiers is insufficient on its own.
