From 28ced9a84cd2f9fc68a081fb3b34e70c5d459be3 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 3 Sep 2018 13:12:15 -0400 Subject: pNFS: Don't allocate more pages than we need to fit a layoutget response For the 'files' and 'flexfiles' layout types, we do not expect the reply to be any larger than 4k. The block and scsi layout types are a little more greedy, so we keep allocating the maximum response size for now.
