Add a trace point "smb3_qfs_done" Which displays: stat-68950 [008] ..... 1472.360598: smb3_qfs_done: xid=14 sid=0xaa9765e4 tid=0x95a76f54 unc_name=\\localhost\test rc=0 Reviewed-by: Shyam Prasad N Signed-off-by: Steve French --- diff --git a/fs/smb/client/smb2ops.c b/fs/smb/client/smb2ops.c index e3dd698854d6..d9eda2e958b4 100644 --- a/fs/smb/client/smb2ops.c +++ b/fs/smb/client/smb2ops.c @@ -2683,6 +2683,7 @@ smb2_queryfs(const unsigned int xid, struct cifs_tcon *tcon, smb2_copy_fs_info_to_kstatfs(info, buf); qfs_exit: + trace_smb3_qfs_done(xid, tcon->tid, tcon->ses->Suid, tcon->tree_name, rc); free_rsp_buf(buftype, rsp_iov.iov_base); return rc; } diff --git a/fs/smb/client/trace.h b/fs/smb/client/trace.h index e671bd16f00c..a7e4755bed0f 100644 --- a/fs/smb/client/trace.h +++ b/fs/smb/client/trace.h @@ -691,7 +691,7 @@ DEFINE_EVENT(smb3_tcon_class, smb3_##name, \ TP_ARGS(xid, tid, sesid, unc_name, rc)) DEFINE_SMB3_TCON_EVENT(tcon); - +DEFINE_SMB3_TCON_EVENT(qfs_done); /* * For smb2/smb3 open (including create and mkdir) calls
