cifs: Add tracing for the cifs_tcon struct refcounting Add tracing for the refcounting/lifecycle of the cifs_tcon struct, marking different events with different labels and giving each tcon its own debug ID so that the tracelines corresponding to individual tcons can be distinguished. This can be enabled with: echo 1 >/sys/kernel/debug/tracing/events/cifs/smb3_tcon_ref/enable Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Paulo Alcantara (Red Hat) <pc@manguebit.com> cc: Shyam Prasad N <nspmangalore@gmail.com> cc: linux-cifs@vger.kernel.org cc: linux-fsdevel@vger.kernel.org Signed-off-by: Steve French <stfrench@microsoft.com>

smb3: add dynamic trace point for ioctls It can be helpful in debugging to know which ioctls are called to better correlate them with smb3 fsctls (and opens). Add a dynamic trace point to trace ioctls into cifs.ko Here is sample output: TASK-PID CPU# ||||| TIMESTAMP FUNCTION | | | ||||| | | new-inotify-ioc-90418 [001] ..... 142157.397024: smb3_ioctl: xid=18 fid=0x0 ioctl cmd=0xc009cf0b new-inotify-ioc-90457 [007] ..... 142217.943569: smb3_ioctl: xid=22 fid=0x389bf5b6 ioctl cmd=0xc009cf0b Signed-off-by: Steve French <stfrench@microsoft.com>

smb: client: allow creating special files via reparse points Add support for creating special files (e.g. char/block devices, sockets, fifos) via NFS reparse points on SMB2+, which are fully supported by most SMB servers and documented in MS-FSCC. smb2_get_reparse_inode() creates the file with a corresponding reparse point buffer set in @iov through a single roundtrip to the server.

smb3: add trace point for queryfs (statfs) In debugging a recent performance problem with statfs, it would have been helpful to be able to trace the smb3 query fs info request more narrowly. 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 <sprasad@microsoft.com> Signed-off-by: Steve French <stfrench@microsoft.com>

cifs: new dynamic tracepoint to track ses not found errors It is perfectly valid to not find session not found errors when a reconnect of a session happens when requests for the same session are happening in parallel. We had these log messages as VFS logs. My last change dumped these logs as FYI logs. This change just creates a new dynamic tracepoint to capture events of this type, just in case it is useful while debugging issues in the future.
