From 50bf73796e85ed6a061df6d8474f7cef7870df6a Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Wed, 4 Jan 2012 11:39:51 +0000 Subject: xenbus: maximum buffer size is XENSTORE_PAYLOAD_MAX Use this now that it is defined even though it happens to be == PAGE_SIZE. The code which takes requests from userspace already validates against the size of this buffer so no further checks are required to ensure that userspace requests comply with the protocol in this respect.
