From 56e4ebf877b6043c289bda32a5a7385b80c17dee Mon Sep 17 00:00:00 2001 From: Bryan Schumaker Date: Wed, 20 Oct 2010 15:44:37 -0400 Subject: NFS: readdir with vmapped pages We can use vmapped pages to read more information from the network at once. This will reduce the number of calls needed to complete a readdir.
