From dd97fddedc251eb423408d89f2947eff9c4ea3c1 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Wed, 26 Feb 2014 17:16:27 -0500 Subject: [PATCH] nfsd4: no need for encode_compoundres to adjust lengths xdr_reserve_space should now be calculating the length correctly as we go, so there's no longer any need to fix it up here.
