CIFS: Print message when attempting a mount
Currently, no messages are printed when mounting a CIFS filesystem and
no debug configuration is enabled.
However, a CIFS mount information is valuable when troubleshooting
and/or forensic analyzing a system and finding out if was a CIFS
endpoint mount attempted.
Other filesystems such as XFS, EXT* does issue a printk() when mounting
their filesystems.
A terse log message is printed only if cifsFYI is not enabled. Otherwise,
the default full debug message is printed.
In order to not clutter and classify correctly the event messages, these
are logged as KERN_INFO level.
Sample mount operations:
[root@corinthians ~]# mount -o user=administrator //172.25.250.18/c$ /mnt
(non-existent system)
[root@corinthians ~]# mount -o user=administrator //172.25.250.19/c$ /mnt
(Valid system)
Kernel message log for the mount operations:
[ 450.464543] CIFS: Attempting to mount //172.25.250.18/c$
[ 456.478186] CIFS VFS: Error connecting to socket. Aborting operation.
[ 456.478381] CIFS VFS: cifs_mount failed w/return code = -113
[ 467.688866] CIFS: Attempting to mount //172.25.250.19/c$
