From b75ad4cda5a6cd3431b1c65c2739c5ebd2c4b9da Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 29 Nov 2012 17:27:47 -0500 Subject: NFSv4.1: Ensure smooth handover of slots from one task to the next waiting Currently, we see a lot of bouncing for the value of highest_used_slotid due to the fact that slots are getting freed, instead of getting instantly transmitted to the next waiting task.
