An administrator cannot take action on these messages, but the
reported errors might be helpful for troubleshooting. Transition
them to trace points so these events appear in the trace log and
can be easily lined up with other traced NFS client operations.
Examples:
append_writer-6147 [000] 80.247393: bl_pr_key_reg: dev=8,0 (sda) key=0x6675bfcf59112e98
append_writer-6147 [000] 80.247842: bl_pr_key_unreg: dev=8,0 (sda) key=0x6675bfcf59112e98
umount.nfs4-6172 [002] 84.950409: bl_pr_key_unreg_err: dev=8,0 (sda) key=0x6675bfcf59112e98 status=RESERVATION_CONFLICT
