Subject: nfsd: Remove write permission from file content
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ec1686761753ead775e9474a6265323a4c555bc6;p=linux.git

nfsd: Remove write permission from file content

The write function doesn't be implemented in file content, and it's meaningless
to write data into this file directly. Remove write permission from it.
