Subject: [PATCH 0/4 V2] Avoid quadratic search when freeing delegations
Date: Mon, 30 Apr 2018 14:31:30 +1000	[thread overview]
Message-ID: <152506256513.7246.13171564155614823841.stgit@noble> (raw)

Following review from Mathieu (thanks) I've made some revisions
and split this into four patches.  The RCU change is now in patch 3
by itself.
I've also revised the description in the main (final) patch quite
a bit.

Thanks,
NeilBrown

NeilBrown (4):
      NFS: slight optimization for walking list for delegations
      NFS: use cond_resched() when restarting walk of delegation list.
      rculist: add list_for_each_entry_from_rcu()
      NFS: Avoid quadratic search when freeing delegations.
