From 03f318ca652889a1aa407e7088b9a2f6a14ae374 Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Fri, 8 Jun 2018 12:28:47 -0400 Subject: nfsd4: extend reclaim period for reclaiming clients If the client is only renewing state a little sooner than once a lease period, then it might not discover the server has restarted till close to the end of the grace period, and might run out of time to do the actual reclaim. Extend the grace period by a second each time we notice there are clients still trying to reclaim, up to a limit of another whole lease period. Signed-off-by: J.
