    smb3: add dynamic trace point for query_info_enter/done · d42043a6
    Steve French authored
    Adds dynamic trace points for the query_info_enter
    and query_info_done (no error) case.  We only had one
    existing trace point related to this which was on query_info
    errors.  Note that these two new tracepoints are for the
    non-compounded query_info paths.
    
    Sample output (from: trace-cmd record -e smb3_query_info*)
    
              ls-24140 [001] .... 27811.866068: smb3_query_info_enter: xid=7 sid=0xd2d00587 tid=0xb5441939 fid=0xcf082bac class=18 type=0x1
              ls-24140 [001] .... 27811.867656: smb3_query_info_done: xid=7 sid=0xd2d00587 tid=0xb5441939 fid=0xcf082bac class=18 type=0x1
