From e36cd4a2873c398ba188f16e4087cce7f00a1506 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 24 Apr 2008 16:59:30 -0400 Subject: nfsd: don't allow setting ctime over v4 Presumably this is left over from earlier drafts of v4, which listed TIME_METADATA as writeable. It's read-only in rfc 3530, and shouldn't be modifiable anyway. Signed-off-by: J.
