Subject: nfsd4: leave reply buffer space for failed setattr
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=725e71de82a2ab297c35819ded9c88eef012eaf8;p=karo-tx-linux.git

nfsd4: leave reply buffer space for failed setattr

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.
