[PATCH 3.14 074/158] nfsd4: leave reply buffer space for failed setattr

From: Greg Kroah-Hartman
Date: Sun May 04 2014 - 12:38:01 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: "J. Bruce Fields" <bfields@xxxxxxxxxx>

commit 04819bf6449094e62cebaf5199d85d68d711e667 upstream.

This fixes an ommission from 18032ca062e621e15683cb61c066ef3dc5414a7b
"NFSD: Server implementation of MAC Labeling", which increased the size
of the setattr error reply without increasing COMPOUND_ERR_SLACK_SPACE.
