Since we're still limiting attributes to a page, the result here is that a large getattr result will return NFS4ERR_REP_TOO_BIG/TOO_BIG_TO_CACHE instead of NFS4ERR_RESOURCE. Both error returns are wrong, and the real bug here is the arbitrary limit on getattr results, fixed by as-yet out-of-tree patches. But at a minimum we can make life easier for clients by sticking to one broken behavior in released kernels instead of two.... Trond says: one immediate consequence of this patch will be that NFSv4.1 clients will now report EIO instead of EREMOTEIO if they hit the problem. That may make debugging a little less obvious. Another consequence will be that if we ever do try to add client side handling of NFS4ERR_REP_TOO_BIG, then we now have to deal with the “handle existing buggy server” syndrome.
