From 4a77118cd5018fec11bf86f6f8d659352ad9a92b Mon Sep 17 00:00:00 2001 From: Steve French Date: Wed, 5 Oct 2005 15:14:33 -0700 Subject: CIFS: Allow wsize to exceed CIFSMaxBufSize This allows cifs_writepages to send data in larger chunks from the page cache, without requiring larger memory allocations in other cases.
