From 172c85dd5764d2766bfd68621e5b54e85c4a6cfa Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Sun, 30 May 2010 11:53:12 -0400 Subject: nfsd4: treat more recall errors as failures If a recall fails for some unexpected reason, instead of ignoring it and treating it like a success, it's safer to treat it as a failure, preventing further delgation grants and returning CB_PATH_DOWN. Also put put switches in a (two me) more logical order, with normal case first. Signed-off-by: J.
