This series of patches is a module that exports Xen Hypervisor attributes
to sysfs. The directory structure created is:
+---sys
+---hypervisor
+---xen
+---version
+---major
+---minor
+---extra
+---compilation
+---by
+---date
+---compiler
+---properties
+---changeset
+---capabilities
+---virt_start
+---translated_pm
+---writable_dt
+---writable_pt
The xen_sysfs module has a tri-state Kconfig so it can be built-in or
loaded as a module.
The module is in three patches:
Patch 1 (this patch) is a Xen file that is used by all OS kernels that run
on Xen. This includes linux, NetBSD, FreeBSD, Solaris, and others. Patch 1
adds #defined constants so that linux users of this file can avoid typedefs.
Patch 2 (follows) contains the Kconfig changes necessary to add this module
to the kernel build.
Patch 3 (follows) contains the source for the xen_sysfs module itself.
# HG changeset patch
# User mdday@xxxxxxxxxxxxxxxxxxxx
# Node ID d296aaf07bcb4141c6dc2a1bfa7d183f919c2167
# Parent a05e56904e7e5e86aae5a2e022621caaf7b3a6f5
define constants for array sizes. Allows linux users of this file
to avoid #typedefs. Existing typedefs work as before.
