locking (S)
This controls whether or not locking will be
performed by the server in response to lock requests from the
client.
If locking = no, all lock and unlock
requests will appear to succeed and all lock queries will report
that the file in question is available for locking.
If locking = yes, real locking will be performed
by the server.
This option may be useful for read-only
filesystems which may not need locking (such as
CDROM drives), although setting this parameter of no
is not really recommended even in this case.
Be careful about disabling locking either globally or in a
specific service, as lack of locking may result in data corruption.
You should never need to set this parameter.
Default: locking = yes
