From bbafffd293e47f4cd5f0ae8b91d7d5767b242a5e Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 24 May 2012 16:31:39 -0400 Subject: NFSv4.1: Exchange ID must use GFP_NOFS allocation mode Exchange ID can be called in a lease reclaim situation, so it will deadlock if it then tries to write out dirty NFS pages.
