From: Christoph Hellwig Date: Thu, 14 Nov 2013 13:50:10 +0000 (-0800) Subject: nfsd: export proper maximum file size to the client X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=aea240f4162d50e0f2d8bd5ea3ba11b5f072add8;p=linux-beck.git nfsd: export proper maximum file size to the client I noticed that we export a way to high value for the maxfilesize attribute when debugging a client issue. The issue didn't turn out to be related to it, but I think we should export it, so that clients can limit what write sizes they accept before hitting the server.
