From 668a400e42817e53a203b7b7efafe9755ec4efa6 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 23 Feb 2017 14:53:39 -0500 Subject: [PATCH] NFSv4: fix getacl head length estimation commit 6682c14bbe505a8b912c57faf544f866777ee48d upstream. Bitmap and attrlen follow immediately after the op reply header. This was an oversight from commit bf118a342f. Consequences of this are just minor efficiency (extra calls to xdr_shrink_bufhead).
