[Xen-devel] [PATCH][TOOLS] libxc: mmap fixes for BSD

[Christoph Egger <Christoph.Egger@xxxxxxx>]

Hi!

On BSD, mmap()ing files works on on-disk files but not on
pseudo filesystems like kernfs or procfs.
Therefore, attached patch mmap()s anonymous memory.

Linux equivalents are sysfs and procfs to above BSD's pseudo-filesystems.
On Linux, mmap is implemented for sysfs but it is questionable to me
how write operations work since (most) files in sysfs have
static content. So this patch may fix some problems
with a Linux Dom0, too.
