From a85857633b04d57f4524cca0a2bfaf87b2543f9f Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Wed, 25 Apr 2018 13:26:23 -0400 Subject: nfsd4: support change_attr_type attribute The change attribute is what is used by clients to revalidate their caches. Our server may use i_version or ctime for that purpose. Those choices behave slightly differently, and it may be useful to the client to know which we're using. This attribute tells the client that. The Linux client doesn't yet use this attribute yet, though. Reviewed-by: Jeff Layton Signed-off-by: J.
