smb3: add trace point for SMB2_set_eof
In order to debug problems with file size being reported incorrectly temporarily (in this case xfstest generic/584 intermittent failure) we need to add trace point for the non-compounded code path where we set the file size (SMB2_set_eof). The new trace point is: "smb3_set_eof" Here is sample output from the tracepoint: TASK-PID CPU# ||||| TIMESTAMP FUNCTION | | | ||||| | | xfs_io-75403 [002] ..... 95219.189835: smb3_set_eof: xid=221 sid=0xeef1cbd2 tid=0x27079ee6 fid=0x52edb58c offset=0x100000 aio-dio-append--75418 [010] ..... 95219.242402: smb3_set_eof: xid=226 sid=0xeef1cbd2 tid=0x27079ee6 fid=0xae89852d offset=0x0 Reviewed-by: Paulo Alcantara (SUSE) <[email protected]> Signed-off-by: Steve French <[email protected]>
