Subject: [PATCH] mars: generic pre-patch for mars
|
|
|
|
Mostly introduces missing EXPORT_SYMBOL().
|
|
Should have exactly zero impact onto the kernel.
|
|
|
|
This is the generic version which exports all sys_*() system
|
|
calls. This should not introduce any additional maintenance pain
|
|
because that interfaces has to be stable anyway due to POSIX etc.
