I am disturbed by the introduction of #defines like current_vps() and
vps_utsname.
Magic lower case #defines are usually a bad idea.
It is not magic defines, this is done intentionally.
You can take a more detailed view into OpenVZ sources, but the idea is
to make kernel compilable without virtualization.
When virtualization is OFF all this macros are defined to trivial
variables/defines which make it an old good kernel.
For example current_vps() should be (&init_vps), i.e. host system
environment only.
vps_utsname will be defined as system_utsname and so on.
These defines hide the cost of the operations you are performing.
At that point you might as well name the thing system_utsname
so you don't have to change the code.
You mean to have variable and define with the same names?
it is not always good. It works fine, when both are defined in the same
file, but poorly when it is scattered all around...
And of course you failed to change several references to
system_utsname.
which one? Maybe intentionally? ;-)
