[ Upstream commit 3caf91757ced158e6c4a44d8b105bd7b3e1767d8 ]
Now when a read delegation is given, two delegation related traces will be printed:
nfsd_deleg_open: client 5f45b854:e6058001 stateid 00000030:00000001 nfsd_deleg_none: client 5f45b854:e6058001 stateid 0000002f:00000001
Although the intention is to let developers know two stateid are returned, the traces are confusing about whether or not a read delegation is handled out. So renaming trace_nfsd_deleg_none() to trace_nfsd_open() and trace_nfsd_deleg_open() to trace_nfsd_deleg_read() to make the intension clearer.
The patched traces will be:
nfsd_deleg_read: client 5f48a967:b55b21cd stateid 00000003:00000001 nfsd_open: client 5f48a967:b55b21cd stateid 00000002:00000001
