commit 5d2f0b1083 upstream.
Steve French reported ksmbd set fixed value to volume serial field in
FS_VOLUME_INFORMATION. Volume serial value needs to be set to a unique
value for client fscache. This patch set crc value that is generated
with share name, path name and netbios name to volume serial.

While we are working through detailed security reviews
of ksmbd server code we should remind users that it is an
experimental module by adding a warning when the module
loads. Currently the module shows as experimental
in Kconfig and is disabled by default, but we don't want
to confuse users.
Although ksmbd passes a wide variety of the
important functional tests (since initial focus had
been largely on functional testing such as smbtorture,
xfstests etc.), and ksmbd has added key security
features (e.g. GCM256 encryption, Kerberos support),
there are ongoing detailed reviews of the code base
for path processing and network buffer decoding, and
this patch reminds users that the module should be
considered "experimental."
