maximum memory size allocated by _xmalloc
Hi all,
I''m currently inserting my own code to adjust the several existing memory
ballooning works.
To accomplish it, I manage some kind of statistics in Xen memory area.
Using _xmalloc, I''ve allocated certain size of memory chunk for the data
structure. ( I varied it from 10kb to 24 MB.)
When the size is equal to 24 MB, xen won''t boot anymore. (stuck during the
xmalloc, according to my debugging. _xmalloc returns NULL.)
There was no problem when the size is be...

[PATCH 0 of 4] Minios improvements for app development
This patch series contains a set of patches making minios rather easier
to use, from an application development point of view.
Overview of patches:
1 Command line argument parsing support, from Xen.
2 Weak console handler function.
3 Build system tweaks for application directories.
4 Trailing whitespace cleanup. (because it is very messy)
Patch 4 is likely to be more controversial than
