Subject: nfsd v4.1 lOCKT clientid field must be ignored
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b7c66360dc34e64742edabf4dc410070aa883119;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

nfsd v4.1 lOCKT clientid field must be ignored

RFC 5661 Section 18.11.3

   The clientid field of the owner MAY be set to any value by the client
   and MUST be ignored by the server.  The reason the server MUST ignore
   the clientid field is that the server MUST derive the client ID from
   the session ID from the SEQUENCE operation of the COMPOUND request.
