Subject: [PATCH v2 0/2] nfsd: move delegated timestamps to being runtime
 disabled instead of compile time

Small update: The kernel test robot reported that this didn't build when
CONFIG_NFSD_V4 was disabled. The fix is to compile out the new debugfs
file when that's the case. Resending both patches, but the second patch
is identical.
