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
